The best Clay colours, compared.
Top pick: Kitojoy polymer clay, 66 colours Best value: QMAY air-dry clay, 24-colour title – Lowest shelf price among multi-colour air-dry kits, at about £6.79, not the highest score. Updated October 2026.
Clay colour, for a UK shopper on amazon.co.uk, is coloured modelling clay. You buy it as a light air-dry kit, a single-colour air-dry bag, a non-hardening slab, or an oven-bake polymer pack. Quality starts with the setting system, not the colour count. Air-dry clay firms as it loses water and stays porous. Polymer clay stays soft until it is baked at the temperature on its own packet. Non-hardening clay never hardens. If you will not use an oven, do not buy polymer. If the piece must stay soft, buy non-hardening clay. For earrings that must survive handling, baked polymer is the durable system and air-dry is the more brittle one. Those checks are in the [clay colour buying guide](/hub/paints-and-varnishes/clay-colour/sub/clay-colour-buying-guide). A minimum age must be visible before you buy, in English. Toys for children under 14 sit under the Toys (Safety) Regulations 2011. Hooks, bells, and plastic tools are a choking issue under 36 months. Air-dry clay is not waterproof, and finished clay is not a plate. This category was not lab-tested.

Personal buying guide
Question 1 of 2
Will you use an oven?
Kitojoy model 2210318 is listed at £19.99 with 4.8 from 32 reviews and 16 UK texts in the file. The bullet counts 66 blocks as 54 colours plus extra red, yellow, blue, white, and black, at 20 g each, while one review says the blocks are 30 g. The age field says Kid, and the bullet asks for adult supervision with young children. The box includes 14 sculpting tools, a silicone mat, and jewellery findings, at a stated 1.85 kg. Reviewers treat it as a starter that shows which colours to buy in larger packs later, and one adult buyer noted that it is aimed at children and still used it. No bake temperature is printed, the special-oven question is unanswered, and the wet-jewellery question is unanswered. A 4.8 from 32 reviews is not a stronger result than FIMO Soft’s 4.7 from 11,053. Take it if you want the mat and the findings and will read the booklet for the bake.
Pros
Cons
Best for: A supervised starter kit with a mat and findings, when you will take the bake time from the booklet in the box.
Less suitable: A top-pick decision based on stars alone, or a household that will not use an oven.
Specifications
Common questions
Does it need a special oven?
The listing question is unanswered. The title says oven-bake. No temperature is printed in the captured bullets.
Can finished jewellery get wet?
The listing question is unanswered. Nothing in the saved listing states a water result.
Are there 66 different colours?
The bullet says 66 blocks: 54 colours, plus extra red, yellow, blue, white, and black. One review says 30 g blocks; the bullet says 20 g.
Staedtler FIMO Soft, model 8023 C12-1, is twelve 25 g blocks in basic colours at £8.00, rated 4.7 from 11,053 reviews, and the listing shows rank 1 in Modelling Compounds. The 50 texts in the saved listing are from the United Kingdom. Reviewers call it a starter pack they were willing to put in a home oven, say the colours mix, and say a hardened piece is durable in small hands. The clay is firm until you knead it, which is the practical limit in a sample that is otherwise praise. The age field says Adult, the non-toxic question is unanswered, and this saved listing does not print a bake temperature even though the item type is oven-hardening. The box is the blocks plus an instruction leaflet, with no sculpting tools, and the item weight is 340 g. It is the top pick here if you will use an oven and want a named maker with the widest review base in the set.
Pros
Cons
Best for: A first polymer project when you will use a home oven and want a named maker with a large UK review base.
Less suitable: Anyone who will not bake, or a household that wanted tools, findings, and dozens of colours in the same box.
Specifications
Common questions
Does this FIMO pack need an oven?
The item type is oven-hardening modelling clay. The listing question about drying in the oven is unanswered, and the saved listing does not give a temperature.
Who is the age field for?
The age field says Adult. The bullets also say children and adults. One UK review describes a gift for a 7-year-old.
Are tools included?
The included components are FIMO blocks and an instruction leaflet. No sculpting tools are listed.
Aestd-ST air-dry clay, model LZL AIR 66SE, is 66 colours at £20.99, rated 4.7 from 2,232 reviews, with 36 UK texts in the file. The pack is 907 g, measuring 22.9 x 19.1 x 10.2 cm, and it includes an instruction booklet, four sculpting tools, and extra zip-lock bags. The bullet claims ASTM D-4236, ASTM F963-17, CPSIA, and EN71, and it recommends children aged 3 and older as well as teens and adults. UK reviewers describe hours of play for more than one child, repeat buying, and small packets that stay soft if you use the seal bags. The same reviews say opened clay dries very quickly in the air, and the bullets themselves do not give a dry time. It is the strongest independent air-dry review base in this set once the duplicated QMAY count is set aside. Skip it if £20.99 is more than you meant for light portions you must reseal.
Pros
Cons
Best for: A 66-colour air-dry kit with a large independent review base, if you will reseal each portion and the £20.99 price is acceptable.
Less suitable: A kiln-free sculpture in one body colour, an oven jewellery project, or a cheaper first kit.
Specifications
Common questions
What age is printed?
The bullet recommends children 3 and older. The age field also lists teens and adults.
Which standards does the bullet name?
ASTM D-4236, ASTM F963-17, CPSIA, and EN71. It also says gluten-free.
Does the listing say how long it takes to dry?
The bullets do not give a time. UK reviews say opened clay dries very quickly in the air unless it is resealed.
The Original Plasticine yellow slab, model PLF01511, is 400 g at £4.80 on amazon.co.uk, rated 4.6 from 18 reviews. Flair Leisure Products makes it in Thailand, and the bullets say it does not shrink or harden and never dries out. The one United Kingdom review in the file says it moulds into shapes and smells less than Plasticine the reviewer remembers from years ago. That single UK text does not name a fault, which is too thin a sample to treat 4.6 as a settled verdict. The age field says Adult, the bullets also mention children, and the non-toxic question is unanswered. You get one yellow colour and no tools, including a stop-motion use that appears in the title only. It stays soft for a model you will reshape, and it will not harden into a school display.
Pros
Cons
Best for: A single yellow block for stop-motion or a model that must stay soft and be reused.
Less suitable: A hard keepsake, a multi-colour kit, or any buy that needs a large UK review sample.
Specifications
Common questions
Will this yellow slab dry hard?
The bullets say it does not shrink or harden and that it never dries out. The special feature is non-drying.
What age is on the listing?
The age field says Adult. The question about age range is unanswered. The bullets also mention children.
How many UK reviews are in the saved listing?
The listing shows 4.6 from 18 reviews. The saved listing contains one United Kingdom review.
Sculpd Premium, model 654321, is 1 kg of stone-grey air-dry clay at £12.99, rated 4.5 from 541 reviews, with the United Kingdom as the stated origin. The bullet says leave it to harden in the air for about 48 hours depending on size and thickness, and that there is no need to fire it. The 50 texts in the saved listing are from the United Kingdom. Reviewers call it soft and silky, including people with painful hands, and say a kilogram covers about two pinch pots or one larger plant pot. Thin parts snap after drying, and one buyer says it breaks more easily than DAS. No tools are listed, no standard is named, and the non-toxic question is unanswered. It is the bag in this set for a kiln-free pot you will paint once it is dry, not a colour kit and not a thin piece you will handle hard.
Pros
Cons
Best for: A kiln-free pot or a small set of pinch pots in stone grey that you will paint after a slow air dry.
Less suitable: A bright colour kit, earrings, or any thin sculpture you expect to survive knocks.
Specifications
Common questions
Can you paint it?
The listing question is unanswered. The bullet says the dried surface is smooth and a joy to paint.
Do you need a kiln?
The bullet says there is no need to fire it. Leave it to harden in the air for 48 hours, depending on size and thickness.
Is a non-toxic claim printed?
The listing question is unanswered. No standard name is in the saved listing.
The orange Plasticine slab, model PLF01311, is 400 g at £4.84, with 4.5 from 479 reviews and 50 United Kingdom texts in the file. Reviewers use it for mould making and for sketching a form before terracotta, and many say it works as advertised once it has been worked. A repeated note is that it feels firmer at first than other Plasticine and becomes malleable as you knead it. The age field says Adult, the question about children is unanswered, and no standard is named. You get one orange colour, measuring 18.5 x 2.5 x 5.6 cm, and no tools. Buy it when the piece has to be reused and must not go hard. It is the wrong slab if you want a keepsake that stays put in a school bag.
Pros
Cons
Best for: Reusable orange clay for moulds, animation, or a sketch you will squash and start again.
Less suitable: A piece that must dry hard, a colour palette, or a gift you expect to last as a solid model.
Specifications
Common questions
Can children use this orange slab?
The listing question is unanswered. The age field says Adult. The bullets talk about children as well as animators.
Is it non-toxic?
The listing question is unanswered. No standard is named in the saved listing.
Does it harden?
The bullets say Plasticine does not shrink or harden and can be used again.
FAGNBED air-dry clay, model NT-02, is a 76-colour set at £11.04, rated 4.4 from 164 reviews, with five sculpting tools and a stated weight of 581 g. The gift bullet says it air-dries completely in 24 hours, is not edible, and is for children over 3. Of the texts in the file, 43 are from the United Kingdom. Reviewers like the small packets, the light dried pieces, and how long children stay occupied, and they describe the texture as foam rather than traditional clay. Some bags arrived a bit dry because the closures are zip-lock rather than sealed packs, and several buyers found the portions smaller than the pictures. The dimensions field prints 10 x 10 x 10 mm, which conflicts with 581 g. No standard number is named. It is a wide palette of light portions if a 24-versus-36 title bothers you, and it is a poor match for dense sculpture clay.
Pros
Cons
Best for: A wide light-clay palette for children over 3 when you accept foam texture and will check the bags on arrival.
Less suitable: A dense pot, a jewellery bake, or a kit you expect to arrive fully sealed and heavy in the hand.
Specifications
Common questions
What age is printed?
The age field says over 3. The kind tip says the clay is not edible and is for children over 3.
Are the dimensions credible?
The saved listing prints 10 x 10 x 10 mm and 581 g. Both are recorded. They conflict.
What do UK reviews say about the texture?
Reviews call it light, soft, and more like foam than traditional clay. Some bags arrived partly dry.
Artecho polymer clay, model ATO-MC5004, is 50 colours at 20 g, five tools and 31 accessories, at £13.98, with 4.4 from 159 reviews. Only 14 UK texts are in the file, and the same texts appear on the 70-colour Artecho listing, so this is not an independent sample. The bullet recommends an oven at 120–130°C for 15–30 minutes and also lists a hair dryer and boiling for small pieces. Reviewers like the colour range for character-scale work, and one text says an oven bake hardened without cracking. Another review says the clay is very hard, tears, and will not stick for fine detail. The age field says Adult, the bullet says not under 3 because of small parts, and the dimensions print 50 x 30 x 10 mm against a stated 1.32 kg. Buy it when you want many colours plus findings and will follow the temperature on this packet.
Pros
Cons
Best for: A first jewellery-style kit when you will use the oven temperature printed on this listing and you accept a small shared review file.
Less suitable: Fine detail if the clay tears for you, a child under 3, or a buy that needs a large independent UK sample.
Specifications
Common questions
How does the listing say you harden it?
Oven bake at 120–130°C for 15–30 minutes is marked recommended. A hair dryer and a boiling method are also listed for small pieces.
Can a toddler use it?
The bullet says it is not suitable for children under 3 because of small parts. The age field says Adult.
What is in the box?
Included components are 50 colours, 5 clay sculpting tools, and 31 accessories.
Artecho model ATO-MC7004 is 70 colours at 20 g for £16.98, and it shows the same 4.4 from 159 reviews and the same review wording as the 50-colour ASIN. The recommended cure on the bullet is again 120–130°C for 15–30 minutes, with a hair dryer and a boiling method also listed. The age field says Adult, and the bullet says it is not suitable under 3 because of small parts. Praise in that shared file is colour range, how far 20 g goes, and a bake that went hard. The criticism is tearing and poor sticking on small work, and the clay needs working before it is soft. The dimensions line prints 50 x 30 x 10 mm beside 1.73 kg, and the best-seller rank numbers match the 50-colour file. It is the larger palette only if you already accept that the star line is not a separate verdict.
Pros
Cons
Best for: Twenty extra colours on top of the Artecho 50-colour kit, once you treat the 4.4 from 159 as one shared file.
Less suitable: A shopper who wants a cheaper entry to the same clay, or proof that 70 colours were reviewed on their own.
Specifications
Common questions
Is the review count separate from the 50-colour set?
This saved listing shows 4.4 from 159 reviews, the same figures as B0G1SVL2VP, and the review text matches. It is recorded as printed.
What cure does the bullet recommend?
Oven bake at 120–130°C for 15–30 minutes. Hair dryer and boiling are also listed.
What age warning is printed?
The age field says Adult. The bullet says not suitable under 3 because of small parts.
Kitojoy model RTSS2210320 is 50 pieces at 25 g, listed at £18.95, with 4.4 from 66 reviews and 21 UK texts in the file. It was first listed on 10 June 2026. The box is a jewellery kit: needles, hooks, bells, jump rings, a silicone mould, and either 14 tools in the bullet or 15 in the title. The bullet recommends oven baking and also lists a hair dryer and boiling, while the conventional-oven question and the cure-time question are unanswered. UK reviewers like it as a starter with many colours, including use by a six-year-old and for group play, and say it softens once warmed. One review calls the tools basic, and another says unsealed clay dries out. The bullet says age 3 and above, the under-8 question is unanswered, and the dimensions print 4.3 x 3.5 x 1.25 cm beside 1.6 kg. It suits an adult who will run the oven, and it is a poor match for a toddler because of the small parts.
Pros
Cons
Best for: An adult-run jewellery starter with findings in the box, if you will follow the booklet rather than a missing temperature.
Less suitable: A toddler, a household with no plan for an oven, or anyone who needs a long review history.
Specifications
Common questions
Can it go in a conventional oven?
The listing question is unanswered. The bullet recommends oven baking and also lists a hair dryer and boiling.
Is it suitable for children under 8?
The question is unanswered. The bullet says age 3 and above. The set includes needles, hooks, and bells.
How long is the cure?
The listing question is unanswered. The bullet points to the instruction booklet and does not print a time.
QMAY air-dry clay, model DNT24, is listed at £6.79 with 4.3 from 2,602 reviews. The title and colour field say 24 colours, a bullet says 36 colours at 0.28 oz each, the unit count is 24, and the number of items is 36. The same review texts appear in the saved listing for the £6.98 QMAY listing, so the 2,602 line is not a separate sample. UK reviewers describe soft, colourful clay that children use for hours and that air-dries solid, with low mess in several texts. They also say pieces are hard to join, opened clay skins over quickly, and the texture is more sponge than play dough. The age field is 3 years and up, the pack is 320 g, and the bullet claims CE and ASTM D-4236. It is the best value here among multi-colour air-dry kits on shelf price, if you can live with the colour clash and reseal as you work.
Pros
Cons
Best for: A low-priced air-dry colour kit for play when you will reseal portions and you do not need one agreed colour count.
Less suitable: A sculpture body, earrings that must be baked, or a buy that depends on a single colour number.
Specifications
Common questions
Is this a 24-colour or a 36-colour set?
The title and colour field say 24. The bullet says 36 colours at 0.28 oz each, the unit count is 24, and the number of items is 36.
Does it need an oven?
The bullet says it does not require oven baking and dries naturally within 24 hours.
What age is printed?
The age field is 3 years and up. The gift line names ages 3 to 9. The school-project question is unanswered.
QMAY model QM-UK-24color-claybag is £6.98, also 4.3 from 2,602 reviews, and the captured UK texts match the £6.79 file. The title says 24 colours, the number of items is 36, and one UK review calls it a 36-colour set. The weight field prints 9 g beside dimensions of 18 x 12 x 5 cm, which cannot both describe a full kit, so both figures stay as printed. Reviewers praise soft moulding for children around 5 to 10 and a booklet a child could follow. They also describe sticky packs, failed joins, and clay that dries while you are still using it. The bullet claims ASTM and CE (EN-71) for age 3 and up. It is the same kind of light air-dry kit as the cheaper QMAY listing, with an extra impossible weight line, so the £6.79 pack is the one to open first if both are in stock.
Pros
Cons
Best for: The same light air-dry play kit as the cheaper QMAY pack, only if this ASIN is the one actually in stock.
Less suitable: Anyone who needs a credible packed weight, a separate review sample, or clay that will not skin over mid-session.
Specifications
Common questions
Why does the weight say 9 g?
The item weight field is 9 g. The dimensions are 18 x 12 x 5 cm. Those two figures conflict, and both are recorded as printed.
Which safety marks are named?
The bullet says the clay complies with ASTM and CE (EN-71) and is for age 3 and up.
How many colours are listed?
The title says 24. The number of items is 36. A UK review in the file calls it a 36-colour set.
Twelve amazon.co.uk clay colour listings were scored from the stored files dated 20 October 2026. There is no lab test. The published score starts with the star average times 20, so 4.7 becomes 94. Review depth then adds 6 at 10,000 reviews or more, 4 from 2,000 to 9,999, and 2 from 400 to 1,999. It subtracts 4 from 50 to 99 reviews and 12 under 50. A shared review file subtracts 6. An unresolved listing conflict subtracts 4. Scores are capped at 100. The top pick is the highest score. The best value is the lowest shelf price among multi-colour air-dry kits, not the highest score. The weights below present those checks as shares of 100.
Star line
78%The base is the amazon.co.uk star average times 20. A 4.7 line scores 94 before review depth, a shared file, or a listing conflict. Stars are the listing average, not a lab test.
Review depth
12%10,000 or more reviews add 6. From 2,000 to 9,999 add 4. From 400 to 1,999 add 2. From 50 to 99 subtract 4. Under 50 subtract 12. A thin high star line is not treated as a stronger result than a much larger sample.
Shared review file
6%Subtract 6 when the captured texts match another ASIN in this set. The two light air-dry listings that share one file, and the two polymer listings that share another, are not independent samples.
Listing conflict
4%Subtract 4 when two printed figures cannot both be true: a colour count, a weight of 9 g on a kit, or dimensions that cannot hold the stated mass. The score is capped at 100.
Start with the setting system, then the age line and small parts, then a cure you can follow, then whether the colour claim matches the bullet. The notes below follow that order. None of these listings was lab-tested.
Clay colour on amazon.co.uk is coloured modelling clay: light air-dry kits, a 1 kg stone-grey air-dry bag, non-hardening slabs, and oven-bake polymer packs. UK buyers are parents, hobby jewellers, and people who want a pot without a kiln. Quality starts with the setting system, not the colour count. Air-dry clay firms as it loses water and stays porous. Polymer clay stays soft until it is baked at the temperature on its own packet. Non-hardening clay is sold because it never hardens.
A 66-colour air-dry kit is not the same weight of clay as twelve 25 g polymer blocks. Two listings say 24 colours in the title and 36 in the body or the item count. Do not state one colour number when the title and the bullet disagree.
Air-dry clay firms as it loses water. One maker’s help page says it needs 24–48 hours and must not be hurried in an oven. Polymer stays soft until it is baked at the temperature on its own packet.
Hair-dryer and boiling lines appear only as bullets on some budget kits. They are not the polymer sheet’s method: 110°C for 30 minutes, a ceiling of 130°C, an oven thermometer, and no food in the same cycle.
If you will not use an oven, do not buy polymer. If the piece must stay soft and be reused, buy non-hardening clay, not air-dry. If you want earrings that survive handling, polymer is the system UK craft guides describe as durable once baked, and air-dry is the system they describe as more brittle.
Toys for children under 14 sit under the Toys (Safety) Regulations 2011. A minimum age must be visible before you buy, in English, with the word Warning. Hooks, bells, and plastic tools are a choking issue under 36 months even when the clay line says 3+. Designated standards include EN 71-1 and EN 71-3. ASTM D-4236 on a bullet is a US art-materials label, not a UK toy approval. The word non-toxic is not that approval either. Cure instructions have to be the ones you can follow.
Three typical situations, each with a recommendation from this comparison.
You want a colour kit and you must read the 3+ line against small tools. The QMAY air-dry kit at about £6.79 is the best value among multi-colour air-dry kits. The title says 24 colours and a bullet says 36. The 4.3 from 2,602 reviews is shared with the other QMAY listing, and opened clay skins over.
You want a pot without a kiln, then paint and a separate glaze. Sculpd Premium is 1 kg of stone-grey air-dry clay at about £12.99, rated 4.5 from 541 reviews. The bullet says about 48 hours in the air and no kiln. Thin parts snap after drying.
Jewellery needs polymer, findings if you want them, and a measured oven. Staedtler FIMO Soft is the top pick at about £8.00, 4.7 from 11,053 reviews. This listing does not print a bake temperature. The age field says Adult, and the box has no sculpting tools.
The top pick is Staedtler FIMO Soft, twelve 25 g blocks, at about £8.00. It scores 100: 4.7 times 20 is 94, plus 6 for 11,053 reviews, and the captured texts are from the United Kingdom. The listing does not print a bake temperature. The best value is the QMAY air-dry kit at about £6.79, the lowest multi-colour air-dry shelf price in this set. The score is 80 after a shared-file deduction and a 24-versus-36 colour clash, so the badge follows the price, not the highest score.
QMAY air-dry clay, 24-colour title
Lowest shelf price among multi-colour air-dry kits, at about £6.79, not the highest score.
