# Play Dough, Putty & Drawing

Base chemistry, not the non-toxic claim on the box, decides everything: wheat-flour dough dries out in hours, silicone putty lasts years, glue-based slime stains and dries, and a drawing board's mechanism decides its mess. Product type sets which facet set applies; age sets how much small-parts risk is acceptable.

## How it works

Play dough is water, salt, and wheat flour softened with oil and a humectant that keeps it pliable; left uncovered it dries into a hard, crumbly lump that can't be reworked, and its wheat content can trigger allergic reactions. Putty and slime both behave as non-Newtonian fluids, flowing like a liquid under slow pressure but resisting or tearing under a sudden one, from different chemistry: putty is a silicone polymer that keeps working for years if the lid goes back on, while slime crosslinks a water-soluble polymer such as PVA glue or guar gum with a borate activator, staying wetter and stickier and eventually drying out or sticking in fabric and hair. Drawing boards skip compounds entirely: a magnetic board lifts iron particles to a stylus and buries them with a slider, while a mechanical board scrapes aluminum powder off a screen with a knob-driven stylus, re-coating it by shaking.

1. **Dough, putty, slime, or drawing board.** Play dough, putty, slime, or a drawing board?
   Dough's chemistry, putty's resistance grade, slime's base, and a drawing board's mechanism are four unrelated fact sets, so this fork decides which facet set to ask about next.
   If play_dough: ask Dough base (wheat or gluten-free), Stays pliable or dries out, Scent or texture mix-in; skip Firmness or resistance grade, Effect variant, Bounces or just stretches, Picks up lint, hair, or carpet fiber, Slime base, Mess and dry-out risk, Mix-in type, Drawing mechanism, What you draw with, Size or portability.
   If putty: ask Firmness or resistance grade, Effect variant, Bounces or just stretches, Picks up lint, hair, or carpet fiber; skip Dough base (wheat or gluten-free), Stays pliable or dries out, Scent or texture mix-in, Slime base, Mess and dry-out risk, Mix-in type, Drawing mechanism, What you draw with, Size or portability.
   If slime: ask Slime base, Mess and dry-out risk, Mix-in type; skip Dough base (wheat or gluten-free), Stays pliable or dries out, Scent or texture mix-in, Firmness or resistance grade, Effect variant, Bounces or just stretches, Picks up lint, hair, or carpet fiber, Drawing mechanism, What you draw with, Size or portability.
   If drawing_board: ask Drawing mechanism, What you draw with, Size or portability, Magnet pieces loose or contained; skip Dough base (wheat or gluten-free), Stays pliable or dries out, Scent or texture mix-in, Firmness or resistance grade, Effect variant, Bounces or just stretches, Picks up lint, hair, or carpet fiber, Slime base, Mess and dry-out risk, Mix-in type.
   Skip if already known: a query that already names 'play dough', 'putty', 'slime', or a drawing-toy brand, an earlier answer naming a compound base or a drawing mechanism.

2. **Minimum recommended age.** How old is the child, given loose magnets or glitter mix-ins?
   The printed minimum age gates small-parts and mouthing risk directly: loose magnets, glitter mix-ins, and bead-filled variants are routinely graded 6+ or 8+ regardless of brand, so a toddler rules most of those out.
   If toddler_0_2: ask Safety or non-toxic certification, Magnet pieces loose or contained; skip Effect variant, Mix-in type, Scent or texture mix-in.
   Skip if already known: an earlier answer naming a child's age or 'toddler', a query that already names an age range like '3+' or '8+'.

## What to surface

### Dough, putty, slime, or drawing board

Which of the four product families this is: modeling dough, silicone putty, glue- or gum-based slime, or a reusable drawing board or mat. Each family is judged on completely different facts: dough on its wheat chemistry and drying behavior, putty on resistance grade and bounce, slime on its base and mess, a drawing board on its erase mechanism. Asking this first avoids asking about bounce on a dough or wheat allergens on a drawing board. [1] [2] [3] [4]

Values: play_dough, putty, slime, drawing_board.
Question to ask: Play dough, putty, slime, or a drawing board?

Used as: top-level split, filter. Data: derived from listing fields, backfill cost low. Look for it as: Derive from the product title and category name ('Modeling Dough', 'Thinking Putty', 'Slime', 'Magnetic Drawing Board').
Title keyword match covers almost every listing; combo sets (dough-and-tools kits) usually lead the title with 'dough' or 'putty'.

### Minimum recommended age

The manufacturer's printed minimum age recommendation, usually tied to a small-parts choking-hazard warning under CPSC and ASTM F963 rules. The real gate is small parts and mouthing risk, not clumsiness: any loose caps, magnet shapes, or bead or glitter mix-ins under 3 carry a choking warning regardless of brand, so the printed age is the fastest way to rule products in or out for a toddler. [6]

Values: toddler_0_2, age_3_plus, age_6_plus, age_8_plus.
Question to ask: How old is the child, given loose magnets or glitter mix-ins?

Used as: top-level split, filter. Data: on the listing, backfill cost low. Look for it as: Standard 'Age Range' or 'Recommended Age' listing field, usually repeated on the front of the pack.
Default to age_3_plus when missing, since CPSIA and ASTM F963 make 3+ the default toy threshold; explicit 'not for under 3' wording flags the toddler exclusion.

### Effect variant

The special effect the putty is sold for: a plain solid color, color-shifting (thermochromic), glow-in-the-dark, magnetic, metallic or glitter, scented, or a clear 'liquid glass' type. The effect is usually the whole reason to buy a second tin once a child already owns a plain one; a maker like Crazy Aaron's organizes its entire catalog around these effects, and some, like the clear liquid-glass type, trade away the classic stretch-and-bounce feel for the effect. [2] [8]

Values: solid_color, color_shifting_thermochromic, glow_in_the_dark, magnetic, metallic_or_glitter, scented, clear_liquid_glass.
Question to ask: Plain color, glow, magnetic, or clear?

Used as: filter, shown on the card. Data: derived from listing fields, backfill cost low. Look for it as: Almost always in the title or collection name ('Liquid Glass', 'Scentsory', 'Magnetic Thinking Putty').
Title and collection-name keyword match; default to solid_color when nothing else is named.

### Drawing mechanism

How marks are made and erased: a magnetic-bead board, a mechanical powder-etch screen, a chalk or dry-erase marker surface, or a water-reveal mat. The mechanism decides the mess and the erase ritual: a magnetic board buries its iron filings with a built-in slider so nothing loose escapes, a mechanical board scrapes aluminum powder that only re-coats when shaken firmly, and a marker or chalk board needs a separate cloth or eraser and can leave dust or stains. [4] [5]

Values: magnetic_bead_board, powder_etch_mechanical, chalk_or_dry_erase_marker, water_reveal_mat.
Question to ask: Magnetic board, scrape-screen, or marker pad?

Used as: filter, shown on the card. Data: derived from listing fields, backfill cost low. Look for it as: Usually implied by the brand or product name ('Magnetic Drawing Board', 'Etch' style screen, 'Dry Erase Pad').
Title and brand keyword match; magnetic and powder-etch boards almost always name their mechanism in the title.

### Dough base (wheat or gluten-free)

Whether the modeling dough's starch is wheat flour, a gluten-free starch (corn or rice based), or unspecified. Traditional dough is wheat-based and can trigger a reaction in a child with a wheat or gluten allergy; it is also not intended to be eaten even though it is labeled non-toxic. Gluten-free starch-based alternatives exist specifically for classrooms and homes with an allergy policy. [1]

Values: wheat_flour_based, gluten_free_starch_based, unspecified.
Question to ask: Need wheat-free dough, or is regular fine?

Used as: filter, shown on the card. Data: derived from listing fields, backfill cost low. Look for it as: Default assumption is wheat-based; 'gluten-free' or 'wheat-free' is called out explicitly in the title when true.
Title keyword match for 'gluten-free'/'wheat-free'; default to wheat_flour_based when the title says nothing, since that is the traditional formula.

### Scent or texture mix-in

Whether the dough is plain, scented, or mixed with glitter, sand, or foam for extra sensory texture. Scent and glitter or sand mix-ins don't change sculpting behavior but do change mess: glitter sheds onto surfaces and textured sand or foam dough crumbles more and is harder to fully reseal, which matters for a tidy classroom versus messy home play. [1]

Values: plain, scented, glitter_or_sparkle, sand_or_foam_textured.
Question to ask: Scented, glittery, or plain dough?

Used as: filter, shown on the card. Data: derived from listing fields, backfill cost low. Look for it as: Almost always in the title ('Scented Dough', 'Sparkle Compound', 'Sand Dough').
Title keyword match; default to plain when the title says nothing.

### Mix-in type

Whether the slime is plain and viscous, or mixed with solid add-ins like beads or charms, or with glitter or metallic flakes. Add-ins are the main way slime brands differentiate otherwise-similar formulas, but solid mix-ins like small charms or beads raise the same small-parts concern as loose toy pieces, so the mix-in type matters for both play variety and the age it's suitable for. [3]

Values: plain_viscous, with_solid_mixins_beads_or_charms, glitter_or_metallic.
Question to ask: Plain, with charms or beads, or glittery slime?

Used as: filter, shown on the card. Data: derived from listing fields, backfill cost low. Look for it as: Almost always in the title ('Glitter Slime', 'Slime with Charms').
Title keyword match; default to plain_viscous when nothing else is named.

### Stays pliable or dries out

Whether the compound stays workable when resealed, or air-dries into a hard, non-reworkable piece if left uncovered. Most dough dries into a hard, crumbly lump once uncovered or the tub lid is lost, so it cannot be reworked into a new shape; buyers who want a compound that lasts across many sessions need to check the lid and seal, not just the 'reusable' claim on the label. [1]

Values: stays_pliable_if_resealed, air_dries_hard_if_exposed.
Question to ask: Reusable for weeks, or fine for one session?

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Rarely stated directly; infer from whether the listing markets an air-dry or bake-to-harden craft use versus a resealable play tub.
Default to air_dries_hard_if_exposed for standard wheat-flour dough tubs, since that is the traditional compound's known behavior.
Chart: position on a shelf-life axis, resealable dough lasting longest.

### Firmness or resistance grade

How much force it takes to stretch the putty: soft and light, medium, firm, or extra-firm resistance. Occupational-therapy and grip-strength brands (TheraPutty, Power Putty) color-code putty by resistance level for hand rehabilitation, and the same idea carries into toy putty: too firm frustrates a young child's hands, too soft loses the stretch-and-snap-back feel an adult using it for a hand workout wants. [2]

Values: soft_light_resistance, medium_resistance, firm_resistance, extra_firm_resistance.
Question to ask: Soft and squishy, or firm resistance?

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Not a structured listing field for toy putty; therapy-grade putty states it directly ('medium resistance') on the package.
Default toy-aisle putty to medium_resistance; only therapy-branded lines reliably state a graded resistance level.
Chart: position on a firmness axis, soft to extra-firm.

### Picks up lint, hair, or carpet fiber

Whether the putty's natural tackiness readily picks up lint, pet hair, and carpet or hair strands on contact. Putty's adhesive quality is handy for lifting dust or glitter off a surface, but it means dropped putty on carpet or long hair picks up fiber or strands that can't be fully cleaned out, which matters more for homes with pets, carpet, or long-haired kids than the usual 'non-toxic' claim does. [2]

Values: picks_up_lint_and_hair_easily, minimal_pickup.
Question to ask: Worried about it sticking to hair or carpet?

Used as: filter, shown on the card. Data: needs research, backfill cost low. Look for it as: Not a listing field; this is a general property of silicone putty rather than a per-product spec.
Default all silicone putty to picks_up_lint_and_hair_easily unless the brand specifically markets a low-tack formula.

### Mess and dry-out risk

How the slime behaves outside its container over time: whether it dries out, sticks in fabric or hair, or washes out cleanly. Unlike silicone putty, slime's polymer network loosens over time and the material dries out or gets stuck in fabric or hair if left outside its container, and the glue-based kind is stickier on first contact. This decides what surface or clothing the mess lands on, more than any non-toxic claim does. [3]

Values: dries_out_if_exposed, sticks_in_fabric_or_hair, washes_out_cleanly.
Question to ask: OK with some staining and mess?

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Not a listing field; infer from reviews or the brand's own care instructions.
Default standard glue-based slime to sticks_in_fabric_or_hair unless the brand specifically markets a washable or mess-free formula.
Chart: position on a mess-risk axis, washable slime lowest.

### What you draw with

Whether the board comes with a magnetic-tipped stylus, a marker or pen, a fingertip-only magnetic bead system, or a chalk stick. Losing the drawing tool usually ends play, so whether the stylus is tethered to the board, a replaceable marker, or built into the mechanism decides how long the toy stays usable and whether lost tips are a recurring cost. [4] [5]

Values: magnetic_tipped_stylus, marker_or_pen_included, chalk_stick, fingertip_only.
Question to ask: Built-in magnetic stylus, or markers or chalk?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Usually in the product description's included-items list.
Match against the mechanism facet: magnetic boards default to magnetic_tipped_stylus, marker and chalk boards state their tool directly.

### Size or portability

Whether the board is a pocket or travel size, a standard tabletop board, or a large easel or floor mat. A travel-size version trades drawing area for fitting in a bag or car seat pocket, while a large easel or floor mat version suits a playroom but won't travel; buyers choosing for a car trip versus a playroom want opposite answers here. [5] [4]

Values: pocket_travel_size, standard_tabletop, large_easel_or_floor_mat.
Question to ask: Pocket travel size, or a bigger board?

Used as: filter, shown on the card. Data: derived from listing fields, backfill cost low. Look for it as: Usually in the title ('Pocket', 'Travel', 'Jumbo', 'Floor Mat') or the product dimensions field.
Title keyword match; default to standard_tabletop when no size word is named.

### Safety or non-toxic certification

Which safety or non-toxic standard the product is certified against: US ASTM F963 toy safety, the ACMI Approved Product (AP) seal for art materials, EU EN 71 toy marking (CE mark), or none stated. ASTM F963 and EN 71 are mandatory mechanical and chemical-migration baselines, but the ACMI AP seal specifically certifies that the compound passed ACMI's own toxicology testing, which matters more for dough, putty, and slime than for a sealed drawing board. [6] [7] [9]

Values: astm_f963_only, acmi_ap_nontoxic, en71_ce, acmi_and_ce, none_stated.

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Rarely a structured listing field; look for the ACMI 'AP' seal image or 'ASTM F963 compliant' wording on the brand's product page.
Check the brand's own product description page for the AP seal image or compliance statement; retail listings almost never carry this as a field.

### Slime base

The polymer the slime is built on: a PVA glue and borate-activator crosslink, or a guar-gum based formula, or unspecified. The glue-and-activator kind starts wetter and stickier and needs the right activator ratio or it stays runny or turns rubbery ('flubber'); guar-gum based slime is the original, less-sticky formula. Buyers adding a separate 'activator' or 'slime powder' refill need to match it to the right base. [3]

Values: pva_glue_borate_crosslink, guar_gum_based, unspecified.

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Rarely stated on a retail listing; DIY slime-making kits are more likely to name the base in the instructions.
Default pre-made retail slime tubs to unspecified; DIY kits sold with a separate activator are almost always pva_glue_borate_crosslink.

### Bounces or just stretches

Whether the putty bounces when dropped and snaps back after stretching, or stretches a little before breaking without bouncing. Standard putty bounces when dropped and resists a slow pull but tears under a sudden sharp one; some effect variants, like clear liquid-glass putty, give up that elasticity entirely, stretching only a bit before breaking and never bouncing, which surprises buyers expecting every tin to behave the same. [2] [8]

Values: bounces_and_snaps_back, stretches_then_breaks_no_bounce.
Question to ask: Want it to bounce, or just stretch?

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Rarely a listing field; the brand's own product description usually says whether a variant bounces.
Default standard-color putty to bounces_and_snaps_back; flag clear or liquid-glass named variants as the no-bounce exception.
Chart: position on a bounce axis, standard putty highest.

### Magnet pieces loose or contained

Whether a magnetic drawing toy's small magnet pieces are loose, separate accessories, or tethered to the stylus and sealed inside the board. Swallowed loose magnets are a more severe hazard than ordinary choking: the 2006 Magnetix recall followed one death and four serious injuries when small magnets came loose, so a toddler-safe magnetic board needs its magnets built in, not sold as separate shapes. [4] [6]

Values: loose_separate_magnet_pieces, tethered_or_sealed_magnets.
Question to ask: Are the board's magnet pieces loose or built in?

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Rarely a listing field; check the product description's included-items list for separate 'magnet shapes' or pieces.
Default classic magnetic boards sold with separate magnet-shape accessories to loose_separate_magnet_pieces; boards with only a tethered stylus tip have no loose pieces.

## What you give up

- Firmer resistance grades, the kind occupational-therapy brands grade for rehab, give an adult's hand more of a workout, but the same firmness just frustrates a toddler who wants a soft, easy squish. [2] Board branch: "Firmer resistance, less easy for small hands".
- Crazy Aaron's own description of its clear Liquid Glass putty says it stretches a bit before breaking and does not bounce, trading the standard putty's elasticity away for transparency. [8] Board branch: "More clarity, no bounce".

## Words you will meet

- **Non-Newtonian fluid**. A material that flows like a liquid under slow pressure but acts like a solid and can tear under a sudden, sharp force.
- **Silicone (PDMS)**. The viscoelastic silicone polymer that gives putty its stretch, bounce, and long shelf life without drying out.
- **Thermochromic**. Changing color with temperature, the effect behind 'color-shifting' putty that reacts to the warmth of your hand.
- **Borate crosslink**. A chemical bridge, often from borax, that links loose glue polymer chains together into a stretchy slime network.
- **Guar gum**. A plant-based thickener that was the original base of Mattel's 1976 Slime, before glue-based recipes became common.
- **PVA glue**. Polyvinyl acetate glue, the white craft glue that, mixed with a borate activator, is the most common modern slime base.
- **Flubber**. A slime made with polyvinyl alcohol instead of guar gum or PVA glue; a different route to the same stretchy result.
- **Humectant**. An ingredient that holds onto moisture, which is why resealed dough stays pliable instead of drying out as fast.
- **ACMI AP seal**. The Approved Product seal from the Art & Creative Materials Institute, awarded after the product passes ACMI's own toxicology testing.
- **EN 71 / CE mark**. The EU's toy-safety testing standard; passing it lets the toy carry the mandatory CE mark required to sell in the EU.
- **ASTM F963**. The US standard consumer-safety specification that toys, including dough, putty, and drawing boards, are tested against.
- **CPSIA**. The 2008 US law that caps how much lead and phthalates children's products sold in the US may contain.
- **Small-parts choking hazard**. A warning required when a toy has pieces small enough to block a child's airway, which drives most age-3-and-under cutoffs.
- **Resistance grade**. A firmness rating, borrowed from hand-therapy putty brands, describing how much force it takes to stretch the material.
- **Stylus**. The pointed tool, often magnet-tipped, used to draw on a magnetic or mechanical drawing board instead of a pen.
- **Magnet ingestion hazard**. The extra danger of swallowed small magnets: the 2006 Magnetix recall followed one death and four serious injuries.

## Where we made a call

- The ACMI AP non-toxic seal is more specific to this category than general ASTM F963 toy-safety compliance. (confidence medium). ACMI's own site names the Approved Product (AP) Seal; Wikipedia confirms the toxicology-testing role. The unsourced 'safe if mouthed' framing was dropped. [7] [6] [9]
