# Oven mitts, pot holders and cooking bags: research notes

Date: 2026-10-25. Scope: hand protection for lifting hot cookware (oven mitts including mini and puppet mitts, five-finger oven and grill gloves, pot holders and hot pads, slip-on pan-handle holders) and bags that food cooks inside (oven and roasting bags, slow-cooker liners, sous vide bags including reusable silicone ones, microwave steam bags); not kitchen towels, aprons, trivets, parchment, foil or silicone mats, or storage and vacuum-sealer bags sold for storage. Taxonomy leaf `supplies > kitchen > oven_mitts`, composing the empty `add-ons/oven_mitt.jsonc` with `kitchen-standard.jsonc` and `supplies-standard.jsonc`.

Overlaps left to siblings: parchment, foil and silicone baking mats and liners (`baking-sheets`); trivets and splatter guards (`cookware-stove-accessories`, which in its own notes leaves "pot holders and silicone handle sleeves" to this leaf); zip and vacuum-sealer bags sold for storage (`household / bags`, `storage-containers`). A zip freezer bag used for sous vide stays with the storage siblings as a product; this register covers it only as a value of `bag_closure` so the sous vide branch can name it. Welding gloves are workwear, not kitchen supplies.

**Scope rule added 2026-10-25 (blind-check fix 9):** a bag counts as this leaf's product only when it is sold and marketed primarily for cooking (oven, slow cooker, sous vide, microwave), not primarily as a food-storage bag. Reusable silicone bags such as Stasher are kept as evidence for `bag_max_temp` and `bag_material` because the brand page itself states oven, microwave and freezer uses; the same SKU may still also appear under `bags` or `storage-containers` when a listing sells it for storage, and that is not a contradiction, just a shared SKU across leaves. Mixed "oven mitts and pot holders set" listings, which have no single `product_form` value, now take the new value `mitt and pot holder set` (see Corrections log).

The leaf bundles two product families that experts treat as unrelated: hand protection (judged by how long it keeps a hand cool on a hot handle, and what happens when it gets wet) and cooking bags (judged by temperature ceiling, venting and seal). One register; split 1 does the dividing and its `cooking bag` branch drops every hand-protection facet.

Quote labels: **verbatim** = the sentence in quotation marks was in text I read myself (curl plus tag stripping, pdftotext, Shopify product JSON, or `innerText` read in a real browser through the chrome-devtools tool); **fetched excerpt** = a fetch tool summarised or reworded the page; **search excerpt** = from a search-engine summary only. Every quote below is **verbatim** unless labelled otherwise. No search excerpts were used: the shared WebSearch budget for this session was already exhausted (200 of 200) when this run started, so every source was reached by a known URL, by on-site navigation or site search, or by the Internet Archive.

## Seed

Seed output, verbatim:

```
=== Example entry (from an unrelated category) ===
category: olive-oil
what this shows: a facet that experts rank first, that almost no listing carries, and that is expensive to backfill. The honest answer is to list it, mark it researched, and limit backfill to the top of the catalog. Also shows a derived metric hanging off a researched facet.

<example>
{
  "id": "harvest_date",
  "label": "Harvest date",
  "definition": "The month and year the olives were picked, as opposed to the best-before date, which is set by the bottler and tells you nothing.",
  "why_experts_care": "Extra virgin oil is a fruit juice and loses the compounds that give it flavour and most of its claimed health effects within about 12 to 18 months of harvest. A bottle with a best-before two years out may already be a year old. People who buy well look for the harvest date and buy within a year of it.",
  "kind": "text",
  "roles": ["annotation", "sort_key"],
  "novice_answerable": false,
  "source": "researched",
  "listing_field_hint": "Rarely present. When it is, it is in a photo of the back label, not a field.",
  "backfill_cost": "high",
  "backfill_note": "Needs a label photo read or a producer page. Backfill the top 100 ranked oils and lazy-load the rest. Where the producer gives only a best-before, record it as unknown rather than guessing.",
  "visual": { "chartable": true, "encoding": "months since harvest on a horizontal scale, with the 12 and 18 month marks drawn" },
  "priority": { "narrows_set": 4, "cost_to_answer": 4 },
  "evidence": ["ucdavis_olive_center", "oliveoiltimes_freshness"]
}
</example>

Derived metric that follows from it:
{
  "id": "months_since_harvest",
  "label": "Months since harvest",
  "formula": "months_between(today, harvest_date)",
  "depends_on": ["harvest_date"],
  "unit": "months",
  "why": "The number a buyer actually needs. Under 12 is fresh. Over 18 and the oil is past the point most tasters would call it extra virgin."
}

=== Persona ===
A pharmacist, who thinks in concentration, delivery form and interactions

Ask yourself two things and write the answers under 'Seed' in notes.md:
  1. What is the oven-mitts equivalent of the example above?
  2. What would this persona notice first about oven-mitts that a typical buyer would not?
Keep what survives the data check. Drop the rest.
```

1. **The harvest-date equivalent** is the tested hold time: how many seconds a mitt keeps a hand comfortable on a handle heated to about 425 to 450 °F. Experts (Wirecutter, Bon Appétit, Serious Eats) rank on it first, no listing carries it, and only a reviewer with a hot skillet and a stopwatch can produce it. The best-before equivalent, the number on the label that tells you little, is the stated maximum temperature ("heat resistant to 932 °F"). Both survived the data check: three reviewers publish hold times, and the same reviewers record products failing or underperforming their stated rating. Kept as `tested_hold_seconds` (researched, high cost, top N only) and `stated_heat_rating` (on the page, with a judgement attached).
2. **What the pharmacist notices first** is dose and route. Dose is temperature times contact time, which is exactly what the hold-time test measures, and the reviewers' own caveat ("the longer you hold a hot pan, the more heat you'll feel") is a dose statement. Route is how heat reaches skin: by conduction through insulation that thins where you squeeze (Bon Appétit: a debossed pattern "allows for even quicker transference of heat if you grab something too tightly"; Wirecutter: the heavy skillet "presses hard into your hand, and you feel the heat quickly"), and by steam through a wet or porous shell. The interaction is water plus heat: a damp cloth mitt or a wet knit glove transfers heat faster. Kept: the liquid behaviour inside `shell_family` (the split), and `insulation_thickness`. Dropped: a skin-burn temperature-time threshold facet (no fetched source in this run, and no listing or reviewer reports it); a "compression resistance" facet (no data anywhere).

## Sources and what each supports

### Regulators

**Regulation (EU) 2016/425 on personal protective equipment, as published on legislation.gov.uk (read in a browser; curl met an AWS WAF challenge)**
https://www.legislation.gov.uk/eur/2016/425/introduction, /article/2, /annex/I
- verbatim, recital (10): "the scope of this Regulation should include PPE for private use against heat, in line with similar PPE for professional use which is already covered by Directive 89/686/EEC. Artisanal decorative products do not claim to fulfil a protective function, are by definition not personal protective equipment and are therefore not concerned by that inclusion."
- verbatim, same recital: products "to protect against damp and water, including but not limited to seasonal clothing, umbrellas and dishwashing gloves, those should also fall outside of the scope of this Regulation."
- verbatim, Article 2(2)(c): the Regulation does not apply to PPE "designed for private use to protect against: (i) atmospheric conditions that are not of an extreme nature, (ii) damp and water during dishwashing". Heat is not in the exclusion.
- verbatim, Annex I: "Category I includes exclusively the following minimal risks: ... (c) contact with hot surfaces not exceeding 50 °C"; "Category II includes risks other than those listed in Categories I and III".
- Supports: oven gloves for home use are PPE in the EU (and in Great Britain, which retains the text), and hot surfaces above 50 °C put them above Category I. Confidence high.

**European Commission, PPE Regulation (EU) 2016/425 Guidelines, 5th edition, October 2025 (PDF, pdftotext)**
https://single-market-economy.ec.europa.eu/document/download/ff1d0861-a59c-4415-94db-48e5631cb866_en?filename=PPE%20Regulation%20%28EU%29%202016_425%20Guidelines%20-%205th%20Edition%20October%202025.pdf
- verbatim: "Protection against heat for private use, for example oven gloves and mitts, was excluded from the previous PPE Directive but is included in the PPE Regulation. Artisanal decorative products which do not claim to protect against heat, for example self-crocheted “potholders” from bazars with decorative function only, are by definition not PPE (see Recital 10)."
- verbatim, categorisation table: "9.15 Protective gloves against heat for private use, including potholders and similar products used for the same purpose as oven gloves and mittens | II"
- verbatim, Article 19 as quoted in the guide: "Category II: EU type-examination (module B) set out in Annex V, followed by conformity to type based on internal production control (module C)".
- Supports: oven mitts and pot holders are Category II PPE, which means a notified body examines the type before sale; decorative potholders are not PPE. Confidence high (second regulator source agreeing with the regulation).

**US eCFR, 21 CFR 177.1630 Polyethylene phthalate polymers (API renderer, curl)**
https://www.ecfr.gov/api/renderer/v1/content/enhanced/current/title-21?part=177&section=177.1630
- verbatim, (f)(2): "The plastics are used for packaging, transporting, or holding food, excluding alcoholic beverages, at temperatures not to exceed 250 °F." with extractives "not to exceed 0.5 mg/in 2".
- verbatim, (h)(1)(i) and (h)(2): "yields chloroform-soluble extractives not to exceed 0.02 milligram/inch 2"; "The plastics are used to contain foods during oven baking or oven cooking at temperatures above 250 °F."
- Supports: the FDA clears PET for oven cooking above 250 °F only in a grade with a 25-fold tighter extractives limit than the grade for holding food up to 250 °F, so a "food-safe" polyester bag is not automatically an oven bag. Confidence high on the text; the reading is ours.

**US eCFR, 21 CFR 177.1500 Nylon resins** (same API)
- verbatim: "The nylon resins listed in paragraph (a) of this section may be safely used to produce articles intended for use in processing, handling, and packaging food"; item 8: "Nylon 612 resins for use only in articles intended for repeated use in contact with food at temperatures not to exceed 212 °F".
- Supports: nylon food-contact clearance is also resin- and use-specific. Confidence high. Cited in the bag-material judgement alongside 177.1630.

### Specialist reviewers who measure

**Wirecutter, The 5 Best Oven Mitts and Pot Holders of 2026 (Internet Archive snapshot 2026-07-22; the live page returns 403 to curl and the fetch tool refuses nytimes.com)**
http://web.archive.org/web/20260722055221/https://www.nytimes.com/wirecutter/reviews/best-oven-mitts-and-pot-holders/
- verbatim, method: "we timed how long each of our contenders was able to protect our hands from heat while we lifted a 400 °F or 450 °F, 12-inch cast-iron skillet by the handle"; "because the skillet is so heavy, it presses hard into your hand, and you feel the heat quickly."
- verbatim, scale: "We’ve tested a total of 33 oven mitts, pot holders, and oven gloves".
- verbatim, results: Homwe Extra Long silicone mitt "hold a 450 °F cast-iron skillet in the air ... for about 40 seconds with two hands"; OXO silicone pot holder "about 13 seconds longer than we could with the Homwe mitt (for a total of 53 seconds)"; Grill Armor gloves "heat-resistant to 932 °F for 12 to 14 seconds. In our tests, we were able to lift a 450 °F cast-iron skillet with two hands for about that long"; G & F Nomex and Kevlar gloves "protected our hands from heat for only about 6 seconds"; Ritz terry potholders "about eight to 10 seconds ... about half as long as ... the OXO pot holder"; Penne Pan Grip "kept our hands comfortable holding a hot cast iron for well over a minute".
- verbatim, ratings: San Jamar 17″ mitt "began to melt and smoke at a markedly lower temperature than its advertised maximum heat-safe temperature of 500 °F"; San Jamar hot pad "melted slightly and began to smoke well below its advertised maximum heat-safe temperature of 500 °F".
- verbatim, materials: "Neoprene, we discovered, stinks and can melt at very high temperatures, so we recommend avoiding it."; "Most of our picks combine waterproof silicone (to keep you from getting burned on a damp mitt), with an inner layer of comfortable, insulating cotton or poly-cotton."; "wet fabric transfers heat much more quickly than dry material"; "Silicone mitts are particularly grippy, but we found them uncomfortable to use unless they have a fabric liner."; "silicone often retains heat for several seconds after being in contact with something hot."
- verbatim, form: gloves "offer more dexterity than a mitt or a pot holder, but they’re less heatproof"; Grill Armor "come in three sizes ... but all of them run a bit large"; "Gloves generally take longer to slip on"; pot holders "might not protect the entire back of your hand or your arm like mitts do, they’re easier to grab in a hurry"; the OXO holder's "oval shape also helps it stay clear of stovetop flames better than holders with corners".
- verbatim, coverage: Homwe "At 15 inches in length ... protects your forearms"; gloves "still don’t offer as much arm coverage as oven mitts"; McDermott: "I’ve actually gotten rack burns from [the Grill Armor Gloves]".
- verbatim, pairs: "Williams Sonoma sells this mitt individually for $20, the same price for a pair of the Homwe Extra Long Professional Silicone Oven Mitts. So if you’d like a pair, you need to spend $40."
- verbatim, handle cover: thickness of the silicone "putting more distance between your hand and the heat"; "The all-silicone handle is dishwasher-safe."; "If you need to lift a pan with two hands, the Penne Pan Grip requires you to use a supplementary mitt"; Lodge Hot Handle Holders "didn’t protect our hands from heat for that long since they were made solely from fabric."
- Supports: hold time as the expert measure, glove versus mitt, wet fabric, neoprene, stated rating unreliable, cuff length, singles versus pairs, handle holders. Confidence high.

**Bon Appétit, best oven mitts (Internet Archive snapshot 2026-08-09; gzip-encoded, decompressed locally)**
http://web.archive.org/web/20260809221017/https://www.bonappetit.com/story/best-oven-mitts
- verbatim, method: "I put a cast-iron skillet in the oven and cranked up the heat to 450º ... I lifted and held the hot skillet handle for as long as possible while using a stopwatch".
- verbatim, styles: "mitten ...; pincer, which has the thumb flap directly opposing the other fingers like a hand puppet ...; and glove, which separates all five fingers. Subcategories of the pincer style are the mini oven mitts, which stop at the wrist rather than covering the forearm".
- verbatim, materials: "Silicone mitts have high heat thresholds (but not always improved duration of protection)"; oven gloves are "usually some kind of fire-resistant fiber knit ... when damp, actually transfer heat to your fingers faster"; "Gloves offer incredible dexterity, but get them wet and they become almost useless as they allow hot steam direct access to your skin."; "Cloth is probably fine for baking and pulling pots off the stove or out of the oven, but saucy and splashy situations might call for silicone."
- verbatim, results: OXO silicone mitt "30-plus seconds", "13-inch length"; Williams Sonoma Ultimate "45 seconds of direct contact", "(15 inches)"; Gorilla Grip "12.5 inches ... (there’s also a longer 14.5-inch mitt available)", "over 30 seconds"; Le Creuset mini mitts "90-plus seconds", "The 8-inch length"; unlined silicone mitts "reduced to about 20 seconds"; Ove Glove "listed as flame-resistant and heat safe up to 540º ... just 13 seconds"; Pit Mitt "only rated to 475º and ... lasted a paltry 13 seconds"; Sur La Table gloves "500º tolerance ... only Sur La Table’s glove gave me anything above 20 seconds"; a quilted cloth mitt "notably thinner on insulation and only lasted 19 seconds"; Cuisinart neoprene grip "melted away smooth when grasping the 450º skillet handle".
- verbatim, coverage: "At 10.5 inches, we’re barely into the long oven mitt category, especially when our winning mini oven mitts are 8 inches."; "you can buy oven mitts in both singles and pairs"; OXO "comes as a single mitt rather than a pair".
- Supports: hold times (second source), glove steam failure, stated rating versus duration, neoprene melting, cuff lengths, singles versus pairs. Confidence high. Note the Le Creuset mini result (90-plus seconds, the longest of the test) is a single outlier and not used as a bound.

**Serious Eats, I Tested 13 Oven Mitts and Pot Holders (read in a browser; curl returned 402)**
https://www.seriouseats.com/best-oven-mitts-pot-holders-5208401
- verbatim, method: "I heated a cast iron skillet in an oven set to 425°F for 10 minutes. I took the temperature of the handle with an infrared thermometer ... I timed how long I could comfortably grasp the handle, reheating the pan to around 300°F each time."
- verbatim, thickness table (sleeve, caliper; seconds held): Williams Sonoma Ultimate 7.8 mm, 44; King Arthur Heavy Duty 8 mm, 41; KitchenAid ribbed pot holder 5.9 mm, 33; Gorilla Grip 5.8 mm, 28.3; OXO silicone mitt 3.3 mm, 28; Matfer Bourgeat leather 2.2 mm, 16.45; Kitchen Mama 2.7 mm, 15.45; Sur La Table gloves 4.7 mm, 11.76.
- verbatim: "In general, the ones that kept my hands the coolest were also the thickest."; "the thicker the mitt, the stiffer it was, which made it difficult to get a secure grip."
- verbatim: "Silicone has a low thermal conductivity."; "Cotton, on the other hand, is highly flammable and isn’t very heat-resistant. Instead of melting like silicone does at high temperatures, it just chars and burns. The Hedley & Bennett pot holders were solely made of cotton, and even though they were thick, they got hot very quickly."
- verbatim: "None of the pot holders offered the same level of protection as oven mitts"; Sur La Table gloves "only protected my hands from a hot cast iron handle for 11.7 seconds, the shortest amount of time of the lineup."; gloves "run large"; Matfer leather "high stated max temperature, I was only able to hold the hot pan handle for 16.45 seconds"; "Mitts with slits in the sleeve ... were easier to put on and remove."; "I wouldn’t recommend most oven mitts directly over an open flame since they are often also made of cotton and polyester, which are more flammable."; "Grill gloves are often made of flame-resistant material and are thicker, longer, and more rugged."
- Supports: hold times (third source), thickness against hold time (single source for the millimetre numbers, kept in these notes only), cotton flammability, grill gloves versus mitts, pot holders versus mitts (disagrees with Wirecutter). Confidence high.

**Serious Eats, Sous Vide Cooking: How to Get Started (browser)**
https://www.seriouseats.com/first-thing-to-cook-with-sous-vide-immersion-circulator-essential-recipes
- verbatim: "it's important to use freezer bags, as the seal on thinner bags (not the lock) can and will degrade and break over long cook times. If you're serious about sous vide, you might want to invest in a vacuum sealer, which will ensure water-tight seals time after time."; "zipper-lock freezer bags will work just fine for most things."; the water displacement method "requires nothing more than a zipper-lock freezer bag and a tub or pot of water".
- Supports: bag_closure on the sous vide branch. Confidence medium (one specialist source; Sirane's vacuum heat-seal bags agree on the vacuum side).

### Primers (definitions only)

**Wikipedia, Oven glove; List of EN standards; Oven bag (raw wikitext)** https://en.wikipedia.org/wiki/Oven_glove, https://en.wikipedia.org/wiki/List_of_EN_standards, https://en.wikipedia.org/wiki/Oven_bag
- verbatim: "Fabric oven mitts usually consist of a layer of thermal insulation surrounded by cotton fabric"; "EN 407: Protective gloves against thermal risks (heat and/or fire)"; "Oven bags should be carefully placed so that the bag does not come in contact with any hot surfaces in the oven, such as heating elements or oven racks. These may cause the bag to melt, smoke, or catch fire."
- Used only for the EN 407 vocabulary line. Not cited for any number. The EN 407 contact-heat levels and temperatures could not be fetched from a primary or manufacturer page in this run, so the register does not state them.

### Retail listings

Amazon and other marketplaces were not fetched (blocked on earlier runs, and the search budget was gone). Fields seen on brand pages: OXO lists length, shell material and washability but no temperature; Grill Armor lists a temperature, materials, size and washability; Lodge lists a temperature per holder; Reynolds lists ceiling, material and size by food weight; Stasher lists ceiling. Because marketplace presence could not be confirmed, every facet except `product_form` is marked `researched`, with low backfill cost where brand pages carry the field.

\* Corrected 2026-10-25: this cell previously showed "~54 (40 + 14)", computed by adding Wirecutter's "about 40 seconds" for the Homwe mitt to "about 14 seconds longer" for Williams Sonoma. Wirecutter never states a direct number for Williams Sonoma; the 54 was the notes author's arithmetic, not a quote, and is dropped per the blind check (finding 1). Williams Sonoma's directly-stated numbers are Bon Appétit's 45 and Serious Eats' 44.

Ranges used in the JSON, corrected after the 2026-10-25 blind check: lined silicone-faced mitts about 15 to 45 s (Kitchen Mama 15.45 and the Le Creuset sleeve-style mitt's 23 at the low end; Williams Sonoma's 44 to 45 at the high end), which overlaps the glove range below. Five-finger knit gloves run about 6 to over 20 s, median about 13 (Wirecutter 12 to 14 and 6; Bon Appétit 13, 13 and above 20; Serious Eats 11.76), with the Sur La Table glove the clearest example of that spread (above 20 s in one test, 11.76 s in another). The computed 54 s figure for Williams Sonoma is dropped (see the data table footnote and the Corrections log). The Le Creuset mini mitt's 90-plus s (a different, mostly-cotton product from the Le Creuset sleeve-style mitt above) remains a kept single-result outlier, noted in the JSON as such.

Price per hand (the derived metric): Wirecutter (Williams Sonoma single at $20 against a Homwe pair at $20) and Bon Appétit (OXO single; "for about the same price as one Oxo, you get a pair" of Gorilla Grip). Formula price / hands covered, where a pair covers 2.

Cuff lengths read: OXO 13 in (OXO page; Bon Appétit), Homwe 15 in (Wirecutter), Williams Sonoma 15 in (Bon Appétit), Gorilla Grip 12.5 and 14.5 in (Bon Appétit), San Jamar 17 in (Wirecutter), a cloth mitt at 10.5 in "barely into the long oven mitt category" and Le Creuset minis at 8 in (Bon Appétit). The JSON states the typical band as text ("full mitts about 13 to 15 in, minis about 8 in"), not as min and max.

Oven-bag ceilings: Reynolds 400 °F / 200 °C (nylon, oven roasting); Sirane Siralon 21 nylon 210 °C (oven roasting); Siralon 10 nylon 180 °C (a microwave/low-temperature/sous-vide film, not an oven-roasting bag — kept out of the oven-bag ceiling claim per the blind check, finding 5); Sirane's polyester oven bags and Toppits' tube state no ceiling at all; Stasher silicone 425 °F / 218 °C; Sirane sous vide bags 120 °C. The JSON now says most oven bags top out about 400 °F (200 to 210 °C), from Reynolds and Sirane, and flags that some makers (Sirane polyester, Toppits) state none.

## Against the existing add-on schema

The add-on `supplies/kitchen/add-ons/oven_mitt.jsonc` is empty (`{}`). The leaf inherits kitchen-standard (`materials[]` with material and role enums, `max_heat_temp`, `dishwasher_safe`) and supplies-standard (`high_signal_markdown`, `sizing` with `size_stated`, `pack_count`, `pieces_included_text`, `dimensions`, `capacity`, `weight`, `measurements_text`). Kinds follow AGENTS.md rule 4: vertical anchor, category quality currency, hard filter, sizing; everything else is markdown.

| Facet | In schema today | Proposed kind | Note |
|---|---|---|---|
| product_form | no | vertical anchor (enum) | Proposal: `item_type` enum [oven_mitt, five_finger_glove, pot_holder, handle_holder, oven_roasting_bag, slow_cooker_liner, sous_vide_bag, microwave_steam_bag, other]. Folds `bag_use` in. Rule 1 says photo-answerable shape stays out, and a photo does tell a mitt from a glove; but the leaf bundles two unrelated families and the bag types are text facts, so the leaf needs this first. Title text, cheap to extract. |
| shell_family | partly: `materials[]` (silicone as exterior_surface, fabric_textile as body) | vertical anchor (existing) | The material enum has no aramid, leather or neoprene, which are three of the five families. Proposal: add `aramid`, `leather` and `neoprene` to the kitchen-standard material enum, and a `lining` role. Then silicone-faced = silicone(exterior_surface) + fabric_textile(lining); grill glove = aramid(body) + silicone(exterior_surface) + fabric_textile(lining). |
| bag_use | no | vertical anchor (part of item_type) | See product_form. |
| tested_hold_seconds | no | outside the schema | Reviewer data, never on a product page. Rule 1 and the schema's "what the page states" scope keep it out. Backfill for the top N from Wirecutter, Bon Appétit and Serious Eats tables into a side table, not the PDP schema. |
| stated_heat_rating | yes: `max_heat_temp` | keep, but not quality currency | It is on the page and buyers see it, so keep the field. It is not the comparable number (all three reviewers found ratings do not predict hold time), so it must not be ranked as currency. Add a comment saying so. |
| insulation_thickness | no | high_signal_markdown | Pages say "thick", "quilted", "lined"; nobody states millimetres. "Lined" versus "unlined" for silicone mitts is the useful text fact; markdown. |
| cuff_length_in | yes: `sizing.dimensions.length` | sizing / hard filter | Bought by number ("13-inch", "15 inch extra long"). Keep in sizing; varies by variant (Homwe regular and extra long). |
| size_range | yes: `sizing.size_stated` | sizing | Gloves only. "One size fits most" versus S/M/L. Already expressible. |
| eu_ppe_marking | no; AGENTS.md rule 5 cuts certifications | high_signal_markdown | Rule 5 cuts certifications, and the house safety rule wants the governing standard visible. Resolve by naming "CE marked as Category II PPE / EN 407" in the `high_signal_markdown` comment as a real safety flag to keep. Not a column. |
| bag_max_temp | yes: `max_heat_temp` | hard filter (existing) | Same field the kitchen-standard comment already calls "the same decision". For bags it is a hard filter: above 400 °F no oven bag qualifies. |
| bag_closure | no | high_signal_markdown | Vent valve, ties, zipper, vacuum heat-seal. Too few products and too varied for an enum. |
| bag_material | partly: `materials[]` (nylon, silicone, plastic) | vertical anchor (existing) | The enum has nylon and silicone but no polyester or PET; Sirane's oven bags are polyester. Proposal: add `polyester_pet` to the material enum. |
| bag_size | partly: `sizing.dimensions`, `sizing.capacity` (lb) | sizing | Reynolds sizes by food weight ("up to 8 pounds", "8 to 24 pounds"); `capacity` with unit lb holds that. Rolls (Toppits 3 m x 31 cm) fit `dimensions`. |

Fields this register considers noise for the leaf: `dishwasher_safe` for fabric mitts and pot holders (they are machine-washed, not dishwashed; the field is right only for all-silicone handle holders and silicone bags, so keep it nullable and leave it null for fabric); `sizing.weight` (no buyer or reviewer compares mitt weight); `sizing.capacity` for anything except bags; `pieces_included_text` (pair versus single is `pack_count`, which matters for price per hand; the rest restates the title); `measurements_text` (AGENTS.md already calls it a dead catch-all).

## Branches

Each leg names the sentence in the register or these notes it follows from.

**Split 1, product_form ("Mitt, glove, pot holder, handle holder, or cooking bag?")**

Answer-to-value rule: the five novice-facing answers map to the facet's values one to one ("glove" is the `five-finger glove` value) — **except** that a buyer describing a double-ended, two-pocket design joined by a strip (the common UK "oven glove") is mapped to `mitt`, not `five-finger glove`. This exception is part of the answer rule itself as of 2026-10-25 (blind-check fix 12), not left to the backfill_note alone. A sixth value, `mitt and pot holder set`, exists for backfill classification of mixed listings only; no cold-start answer selects it directly, the same pattern as `neoprene` in split 2.

- when `cooking bag`: then_ask bag_use; makes_irrelevant shell_family, tested_hold_seconds, stated_heat_rating, insulation_thickness, cuff_length_in, size_range, eu_ppe_marking.
  - bag_use: "Which cooking method the bag is made for; each is a different product" (bag_use definition) and Reynolds: "We do not recommend it [oven bags in a slow cooker]. Try Reynolds Kitchens® Slow Cooker Liners."
  - the seven hand facets: each is defined on a mitt, glove, pot holder or holder (their definitions say "a mitt", "the shell", "the cuff", "glove sizes", "oven gloves and pot holders"); a bag has none of them. stated_heat_rating is the mitt's rating; the bag's own ceiling is the separate `bag_max_temp`.
- when `mitt`: then_ask shell_family, cuff_length_in; makes_irrelevant size_range, bag_use.
  - cuff_length_in: Bon Appétit "mini oven mitts, which stop at the wrist rather than covering the forearm"; Wirecutter Homwe "At 15 inches in length ... protects your forearms" (cuff_length_in, why experts care).
  - size_range irrelevant, corrected 2026-10-25 (blind-check fix 10): this is a scoping choice, not a claim that mitts never vary in size. `size_range` is defined by its own text as "how many hand sizes a five-finger glove comes in," so it is irrelevant to mitts by definition; the earlier note's premise ("every mitt reviewed is one size") is dropped, since Bon Appétit and Wirecutter both flag single-size mitts as a fault, which implies sized mitts exist.
  - bag_use irrelevant: it describes bags (scope). The other four bag facets are reached only through bag_use's branches, so dropping bag_use drops them; they are not listed again to keep the tree readable.
- when `five-finger glove`: then_ask shell_family, size_range, cuff_length_in; makes_irrelevant bag_use (as for mitt).
  - size_range: Wirecutter "all of them run a bit large"; Serious Eats "they run large"; Bon Appétit: one-size Ove Glove and Pit Mitt "too floppy on some of our daintier fingers" (size_range, why experts care).
  - cuff_length_in added 2026-10-25 (blind-check fix 10): McDermott's rack burns were reported through five-finger gloves specifically (Wirecutter: "I've actually gotten rack burns from [the Grill Armor Gloves]"), and Grill Armor sells a "Long Cuff" size. Moved here from the shell_family branch below, since the rack-burn evidence is about gloves, not shell material.
- when `pot holder` or `handle holder`: makes_irrelevant cuff_length_in, size_range, bag_use (as for mitt).
  - cuff_length_in: pot holders "might not protect the entire back of your hand or your arm like mitts do" (Wirecutter); "They don’t protect your wrists, but that’s the nature of pot holders" (Serious Eats). A handle holder covers the handle, not the hand (product_form values). Neither has a cuff.
  - size_range: defined for gloves only.

**Split 2, shell_family ("Silicone-faced, plain cloth, or grill-ready knit or leather?")**

Question reworded 2026-10-25 (blind-check fix 11): "fire-rated knit" was jargon a first-time buyer would not hold a preference about; "grill-ready" names the use instead of the fibre. Answer-to-value rule: "silicone-faced" → `silicone-faced`; "plain cloth" → `all-cloth`; "grill-ready knit or leather" → `aramid knit` or `leather`. `neoprene` is a value no answer selects; it exists so the assistant can warn on it (judgement 3). All-silicone five-finger gloves (no knit shell, e.g. Wirecutter's mention of "Lanon Liquid Silicone Gloves" among the competition) take `silicone-faced`; the backfill_note now says so explicitly.

Rationale reworded 2026-10-25 (blind-check fix 11): "only aramid and leather are meant for open flame" is dropped because it clashed with OXO's own silicone-mitt page ("Durable construction stands up against flames, steam and stains"). The rationale now says aramid knit and leather are *sold for* grills and open flame, a marketing-and-use claim, not an absolute materials claim about what can touch fire.

- when `silicone-faced`: then_ask insulation_thickness.
  - "a silicone face with no fabric liner held about 20 seconds against 30 to 45 for lined ones" is a chain of two stated facts: Bon Appétit unlined silicone mitts "reduced to about 20 seconds" and OXO/Gorilla/Williams Sonoma lined mitts at 30-plus to 45 s (insulation_thickness, why experts care), plus Serious Eats "the ones that kept my hands the coolest were also the thickest".
- `aramid knit` / `leather` branch dropped 2026-10-25 (blind-check fix 10): it used to then_ask cuff_length_in on an unstated step ("the reach is over coals, so the cuff protects the arm") resting on one leather product (Matfer). Rather than patch that chain, the leg is removed; cuff_length_in is already asked for both forms that carry this shell family, via the product_form `mitt` and `five-finger glove` branches above, so nothing is lost.
- No branch for `all-cloth`: Serious Eats found the thick all-cotton Hedley & Bennett holders "got hot very quickly", so thickness does not rescue cloth, and nothing else downstream changes.

**Split 3, bag_use ("Oven roast, slow cooker, sous vide, or microwave?")**

Answer-to-value rule: "oven roast" → `oven roasting`; "slow cooker" → `slow-cooker liner`; "sous vide" → `sous vide`; "microwave" → `microwave steaming`.

- when `oven roasting`: then_ask bag_max_temp, bag_size, bag_closure.
  - bag_max_temp: Reynolds "Do not use for baking or roasting at temperatures above 400°F" (bag_max_temp, why experts care).
  - bag_size: Reynolds large "for foods up to 8 pounds", turkey size "8 to 24 pounds"; Toppits cut "20 cm länger als das Gargut" (bag_size, why experts care).
  - bag_closure: Reynolds "cut six 1/2 inch slits ... so the bag does not burst"; Toppits OptiVit valve lets steam escape (bag_closure, why experts care).
- when `sous vide`: then_ask bag_closure.
  - bag_closure: Serious Eats "use freezer bags, as the seal on thinner bags ... can and will degrade and break over long cook times"; vacuum sealer "will ensure water-tight seals" (bag_closure, why experts care).
  - bag_size irrelevant mark dropped 2026-10-25 (blind-check fix 10): no source says sous vide bag size does not matter, and sous vide bags and rolls are in fact sold by size. The makes_irrelevant entry is removed rather than fixed, since no sourced replacement rule was found in this run.
- when `slow-cooker liner`: makes_irrelevant bag_closure.
  - A liner sits open in the crock under the cooker's lid (bag_closure, why experts care: "Slow-cooker liners have none"); Reynolds' liner page names no closure.
- No branch for `microwave steaming`: the sources (Sirane self-seal steam bags, Stasher's "leave seal open a quarter of a inch") change nothing that is not already in bag_closure for every bag.

Dropped legs: `mitt` → then_ask tested_hold_seconds (it is an annotation for every hand product, so asking it on one branch says nothing); `cooking bag` → then_ask bag_material (bag_use is the better next question; material follows from it).

## Trimmed detail

Facts cut from capped fields; each kept here or elsewhere in the JSON.

- summary: the leaf's two families and the sibling overlaps (scope line above).
- mechanism: Serious Eats' "Silicone has a low thermal conductivity" and the claim that silicone "melts" at high temperature while cotton "chars and burns" (kept in shell_family and judgement 3); Wirecutter's note that silicone "retains heat for several seconds" after contact (kept in the silicone-faced family line).
- tested_hold_seconds.why_experts_care: the three test set-ups differ (Wirecutter and Bon Appétit at 450 °F with a heavy 12-inch skillet held two-handed; Serious Eats at a 425 °F oven, handle measured by infrared and reheated to about 300 °F), so seconds compare within one review, not across. The table above holds the per-product numbers.
- insulation_thickness.why_experts_care: Serious Eats' caliper numbers (7.8 mm sleeve, 44 s; 2.2 mm leather, 16.45 s); single source, so not in the JSON.
- stated_heat_rating.why_experts_care: Matfer leather mitts "high stated max temperature" and 16.45 s (Serious Eats); Pit Mitt "only rated to 475º" and 13 s (Bon Appétit).
- eu_ppe_marking.why_experts_care: Category II means EU type-examination (module B) followed by internal production control (module C); hot surfaces up to 50 °C would be Category I.
- bag_material.why_experts_care: the 21 CFR 177.1500 Nylon 612 limit of 212 °F for repeated use; Sirane's two nylon grades at 180 and 210 °C.
- Reynolds' instruction against countertop roaster ovens, convection and toaster ovens and grills (kept in bag_max_temp's backfill note as "full-size ovens only").
- Handle holders: Lodge says its fabric, silicone and patterned holders are "not intended for use in oven", and its leather one not "while cooking, grilling, or baking" (kept in the handle-holder vocabulary line).
- price_per_hand.hands_covered: pairs count 2, singles count 1; left undefined (not computed) for `mitt and pot holder set` listings and for handle holders, which need a supplementary mitt (Wirecutter: the Penne grip "requires you to use a supplementary mitt"). Added 2026-10-25, blind-check fix 9.

## Corrections

- Script note: when this run started, `schema.json` restricted `vertical` to `formulations, machines, fashion, furnishing, other`, so `validate.py` would have rejected the briefed `"vertical": "supplies"` (as the cookware-sets, cocktail-mixing-tools and frying-pans runs recorded). By 13:45 on 2026-10-25 the skill's `schema.json` had been updated, outside this run, to add `supplies` to the enum. The final category.json validates clean with `supplies`, and a copy with `other` also validates. This run did not modify any script, schema or asset.
- Grill Armor sizing: the product page says "One Size Fits Most"; Wirecutter says the line comes in three sizes and a long cuff. Both recorded; `size_range` treats sizes as per-listing.
- Sirane slow-cooker liner page contradicts itself (polyester title, nylon bullet). Not used for any material claim.

## Corrections after the blind check (2026-10-25)

A blind checker who did not write this register graded it (`check.md`). Each line below is one change made against a numbered finding in its "Required fixes" list, or a reason a finding was not applied as suggested. Re-fetches used `WebFetch`; the shared `WebSearch` budget for this session was still exhausted, matching what the checker itself reported.

1. (Finding 1) Dropped the invented 54 s figure for Williams Sonoma (the notes author's own arithmetic, not a Wirecutter quote) from the data table and the ranges paragraph; added Le Creuset's 23 s and Kitchen Mama's 15.45 s (both lined silicone-faced, Serious Eats) to the table; restated `tested_hold_seconds`'s range, `why_experts_care` and the `summary` as lined silicone-faced mitts ~15–45 s, overlapping gloves, instead of the contradicted "28 to 54".
2. (Finding 2) `judgement` "Five-finger gloves suit quick, dry..." now has `sources_disagree: true` and `confidence: medium`; its note and `product_form.why_experts_care` no longer claim gloves held "the shortest time in every test" (Bon Appétit's 10 s silicone mini mitt and 19 s cloth mitt beat some gloves); restated the glove figure as 6 to over 20 s, median about 13, and noted Bon Appétit's own conclusion that gloves are "perhaps the best option" for most home use.
3. (Finding 3) Removed Grill Armor's 932 °F / 12–14 s as evidence that ratings do not predict hold time, since Wirecutter's test matched the maker's own stated duration — the opposite of the point being made. `judgement` 1 and `stated_heat_rating.why_experts_care` now lead with the Ove Glove (540 °F, 13 s) and Pit Mitt (475 °F, 13 s) examples instead, with Grill Armor kept only as a parenthetical counter-example. Added an instruction to `stated_heat_rating.backfill_note` to store any stated duration alongside the rating.
4. (Finding 4) Replaced the cuff-length mapping ("wrist-length" at 10.5 in or less, contradicted by Bon Appétit calling 10.5 in "barely into the long oven mitt category", and leaving 10.5–13 in unmapped) with a boundary near the 8 in minis: `cuff_length_in.backfill_note` now maps "wrist-length" to about 9 in or less and "forearm" to anything longer, so nothing above 9 in is left unmapped.
5. (Finding 5) Dropped "rules every one out" from `bag_max_temp.why_experts_care`. Corrected `judgement` 7's note: Sirane's 180 °C Siralon 10 is a low-temperature microwave/sous-vide film, not an oven-roasting bag, so only its 210 °C grade supports the oven-bag ceiling; noted that Sirane's polyester oven bags and Toppits state no ceiling at all. Added "record unknown, do not default to 400 °F" to `bag_max_temp.backfill_note`. Re-fetched `reynolds_oven_bags` directly on 2026-10-25 for the "Do not use for baking or roasting at temperatures above 400°F" quote the checker flagged as unfound on either page they read: it is present on the live oven-bag-cooking-guide page, so the quote and its citation are kept rather than dropped.
6. (Finding 6) Removed "so padding does not rescue cloth" from `insulation_thickness.why_experts_care` (it generalised from one Hedley & Bennett cotton pot holder, against Bon Appétit's "cloth mitts can offer the most protection" and its own longest-holding mitt being mostly cotton); restated as a single-test observation about that one product.
7. (Finding 7) Changed `size_range.source` from `researched` to `listing` and `backfill_cost` to `none`: Grill Armor's own product page carries a size selector (One Size Fits Most, Small, X-Large, X-Large Long Cuff), so it is a listing field, not something that needs research. Corrected the `grillarmor_gloves` reference's "Sold as one size fits most" line to name the selector's actual options. Qualified `size_range.why_experts_care`'s "pick two or more sizes if your hands are small" claim, since Serious Eats and Wirecutter both found even labelled-small sizes ran big.
8. (Finding 8) Added `EN 407` (and `EN 420`, the general glove-requirements standard) to the vocabulary and to `eu_ppe_marking.why_experts_care`, sourced to Wikipedia's "List of EN standards" (re-fetched 2026-10-25), stating that exact pass levels were not verified in this run. Replaced the unsourced "before sale in the EU or Great Britain" CE claim with a sourced GB route: fetched gov.uk's "Using the UKCA marking" guidance, which states GB conformity runs through UK Approved Bodies (UKAS-accredited) rather than EU notified bodies, with CE marking still accepted on a label until 31 December 2027. Added both sources to `eu_ppe_marking.evidence` and to the EU/GB `judgement`.
9. (Finding 9) Added a scope rule to notes.md: a bag belongs to this leaf only when sold and marketed primarily for cooking, not primarily as a storage bag; the same SKU (e.g. Stasher) may also appear under `bags` or `storage-containers` without contradiction. Added a new `product_form` value, `mitt and pot holder set`, for mixed listings that have no single value today, and left `price_per_hand`'s `hands_covered` undefined for those and for handle holders.
10. (Finding 10) Dropped the `shell_family` branch leg that asked `cuff_length_in` on `aramid knit` / `leather` (one leather source, an unstated "reach is over coals" step); moved `cuff_length_in` into the `product_form` = `five-finger glove` branch instead, where the actual rack-burn evidence (McDermott's gloves, Grill Armor's Long Cuff size) sits. Dropped the `sous vide` branch's `makes_irrelevant: bag_size` (no source says sous vide bag size does not matter, and sous vide bags are sold by size) without replacing it, since no sourced rule for what to ask instead was found this run. Kept `mitt` → `makes_irrelevant: size_range`, but reworded its justification in notes.md from an empirical claim ("every mitt reviewed is one size", unsourced) to the scoping choice it actually is.
11. (Finding 11) Reworded the `shell_family` question from "fire-rated knit" to "grill-ready knit" (a use a novice can judge, not a fibre name they would not hold a preference about). Softened the split's `rationale` from "only aramid and leather are meant for open flame" (contradicted by OXO's own "stands up against flames" marketing) to "aramid knit and leather are sold for grills and open flame." Added backfill guidance that all-silicone five-finger gloves take `silicone-faced`, and to classify shell family from the brand's materials line rather than title branding, since Bon Appétit found the "Ove Glove" is 100% cotton despite its flame-resistant name; corrected the Ove Glove row in the data table from "aramid-blend knit" to "all-cloth".
12. (Finding 12) Added the UK "double oven glove → `mitt`" mapping directly into split 1's answer-to-value rule in notes.md, not only into `product_form.backfill_note` where it already lived.
13. (Finding 13) Reworded `judgement` 8's note so 177.1630's stricter PET oven-extractives numbers are no longer read onto Reynolds' nylon bag; it now says 177.1500 (nylon, which actually covers Reynolds' bag) has no such oven-specific clause, so clearance is resin- and use-specific. Confidence stays `medium`.
14. (Finding 14) Added to `judgement` 3's note that the same neoprene products that melted or smoked still held 30–45 seconds, as long as many silicone mitts, so the avoid-advice is about melting and smell, not hold time.
15. (Finding 15) Added a `multi-use` value to `bag_use` for silicone bags whose brand page lists several uses, and reworded `bag_use.backfill_note` so a multi-use bag takes that one value instead of being forced into a single-use category it does not single-valuedly belong to.
16. Also fixed `tradeoffs[0].plain`'s "held a hot handle for roughly a third of a lined mitt's time" (a precise fraction the corrected, wider ranges no longer support) to "substantially less time than mitts" (Part D / general honesty note, not independently numbered in "Required fixes").

No finding was rejected outright; finding 5's sub-claim about the unfound Reynolds quote was the only one where re-verification reversed the checker's conclusion rather than confirming it (see item 5 above).
