The best pottery clay for most home potters is a smooth cone 5 stoneware: AMACO No. 46 Buff Stoneware if you want one clay for the wheel and hand-building, or Laguna B-Mix 5 if you mostly throw. Both have low fired absorption on the maker's spec sheet, both are easy to find in the US, and both suit the mid-fire kilns and glazes most beginners use. This guide is research-based: we compared maker spec sheets and dealer listings for cone range, shrinkage and absorption. We did not fire these clays ourselves. Specs checked October 2026.

Pottery clay compared: cone, shrinkage and absorption
Absorption is the share of water a fired piece soaks up. Lower is denser and better for mugs, bowls and plates. Shrinkage is how much smaller a piece gets from wet clay to finished pot. All figures below come from the maker's own page unless noted.
| Clay | Cone range | Shrinkage | Absorption | Best for | Price |
|---|---|---|---|---|---|
| AMACO No. 46 Buff Stoneware | 5 to 10 (best at 5) | 12% at cone 5 | 1.8% at cone 5 | Beginners, wheel and hand-building | Check price |

1. AMACO No. 46 Buff Stoneware: best clay for beginners overall
No. 46 is the clay we would point a first-time buyer toward, based on its spec sheet. AMACO rates it from cone 5 to cone 10 and says it gives its best results at cone 5, the range most home electric kilns and most commercial glazes target. The number that matters most is absorption: AMACO lists 1.8% at cone 5 and 0% at cone 10. That is dense enough for everyday mugs and bowls once you glaze and fire them correctly.
AMACO also says No. 46 suits every hand method (slab, pinch, coil and sculpture) as well as wheel throwing. That matters for beginners, because most people try both before settling on one. One box covers both, and you only need one set of glaze tests. It carries the AP (Approved Product) seal in its moist form.
- Cone range: 5 to 10, best at cone 5 (AMACO also lists a cone 04 bisque)
- Fired color: buff at cone 5, soft gray at cone 10
- Shrinkage: 12% at cone 5, 13.2% at cone 10
- Absorption: 1.8% at cone 5, 0% at cone 10
- Size: 50 lb moist box (AMACO item 46-M)
- Price band: about $45 to $60 per 50 lb box at AMACO list price before shipping in October 2026; Amazon is usually higher because shipping is built in
Pros
- Dense at cone 5 for functional ware
- One clay for wheel and all hand-building methods
- Wide cone 5 to 10 range if you later move to a cone 10 studio
Cons
- Buff color mutes bright underglazes
- 50 lb is the only size AMACO lists, which is heavy to ship
Who should skip it: potters who want a white body under bright colors. Pick Laguna B-Mix 5 or AMACO No. 16 White Chocolate instead.
2. Laguna B-Mix 5: smoothest clay for the pottery wheel
B-Mix is one of the best known throwing bodies in the US, and the cone 5 version carries the same character into mid-fire. Laguna describes WC401 as having a smooth, porcelain texture and says it offers the same characteristics as its cone 10 B-Mix. Smooth, plastic clay stretches as you pull walls without tearing, which helps when you are learning to throw thin, even cylinders.
It fires cream in oxidation, so it shows glaze color better than a buff body, and Laguna lists 2.3% absorption at cone 5. Laguna's site sells it in 50 lb steps (50 to 250 lb per online order), while Amazon listings offer 5, 25 and 50 lb boxes, which helps if you want to try it before committing.
- Cone: 5
- Fired color: cream in oxidation (wet color light gray)
- Shrinkage: 12%
- Absorption: 2.3% (Laguna)
- Texture: smooth, no grog
- Price band: Laguna lists about $0.85 per lb before shipping; Amazon boxes cost more per pound
Source note: Laguna's WC401 page lists 2.3% absorption. A Clay-King listing we recorded in September 2026 showed 2.75%, which is the figure Laguna gives for B-Mix 5 with Grog. We use Laguna's 2.3% for plain B-Mix 5.
Pros
- Very smooth and plastic on the wheel
- Cream fired color
- Small Amazon sizes for a trial
Cons
- Rated for cone 5 only
- No grog, so large hand-built pieces need slow, even drying
Who should skip it: cone 10 studios (use B-Mix 10 instead) and hand-builders making big slab pieces, who will do better with the grogged version below.
3. Laguna B-Mix 5 with Grog: best for hand-building and larger forms
Grog is clay that has already been fired and ground. A little of it opens the clay body so it dries more evenly and stands up better in tall or wide work. Laguna says WC436 uses a very fine grog, which makes it "a more forgiving body with a slight texture and minimal speckling." You keep most of the B-Mix feel but gain some tooth for slabs, coils and bigger thrown forms.
Laguna lists the body for large and medium throwing as well as large hand-building. Shrinkage is a little lower than plain B-Mix 5, which helps flat slabs and tiles stay true. If you plan to switch between the wheel and slab work, this is the B-Mix to buy.
- Cone: 5
- Shrinkage: 11% (Laguna); Blick lists 10.5%
- Absorption: 2.75% (Laguna); Blick lists 2.5%
- Texture: very fine grog, slight texture, minimal speckling
- Price band: Laguna lists about $0.82 per lb before shipping
Spec conflict: Laguna's WC436 page lists 11% shrinkage and 2.75% absorption. Blick's listing for the same clay says 10.5% and 2.5%. The gap is small; we print Laguna's figures as the maker source.
Pros
- Fine grog adds strength for slabs and large forms
- Still throws well
- Cone 5 like the rest of the B-Mix 5 family
Cons
- Slightly rougher on hands during long throwing sessions
- A touch more absorbent than plain B-Mix 5
Who should skip it: throwers who want the smoothest possible feel for small, thin pieces. Plain B-Mix 5 suits them better.
4. Laguna B-Mix 5 with Speckles: best speckled clay
Speckled clay gives the flecked look you see on many handmade mugs, where small iron specks show through a pale glaze. Laguna's WC408 keeps the working properties of standard B-Mix, so you get the look without learning a new clay. Laguna describes it as a smooth, very plastic and workable porcelaneous stoneware.
Two warnings on Laguna's page are worth reading before you buy. First, it says not to fire this clay past cone 5. Second, it asks for slow drying and plenty of compression on rims and bottoms to avoid cracks. Laguna also says it is stocked only at its California facility, so delivery times can be longer in the East.
- Cone: 5 (Laguna: do not fire past cone 5)
- Shrinkage: 12.47%
- Absorption: 2.47%
- Texture: smooth and very plastic, with iron specks
- Price band: Laguna lists about $0.86 per lb before shipping; small Amazon packs cost more per pound
Pros
- Same feel as B-Mix with a decorative speckle
- Low absorption at cone 5
- 5 lb and 10 lb Amazon packs for testing
Cons
- No tolerance for over-firing
- Needs slow drying and compression to avoid cracks
Who should skip it: anyone firing to cone 6 or above, and potters who want a clean, unspecked surface under clear glaze.
5. AMACO No. 16 White Chocolate: lowest absorption stoneware
White Chocolate is part of AMACO's premium mid-range line, rated cone 5 to 7. Its spec sheet stands out: 0.5% absorption at cone 5 and 0.3% at cone 6. That is close to porcelain territory while still behaving like a stoneware. AMACO describes it as smooth, pliable and creamy, and says it is manganese-free.
It comes in 20 lb boxes of four individually wrapped 5 lb blocks. For a home potter that is handy: you open one block at a time and the rest stays sealed. AMACO also notes the clay is thixotropic, which means it softens when you wedge or work it and firms up again when it rests.
- Cone range: 5 to 7
- Fired color: creamy white chocolate tone
- Shrinkage: 13.5% at cone 5, 13.9% at cone 6
- Absorption: 0.5% at cone 5, 0.3% at cone 6
- Size: 20 lb box (four 5 lb blocks)
- Price band: about $40 to $50 per 20 lb box at AMACO list price before shipping
Pros
- Very low absorption at cone 5 and 6
- 5 lb blocks stay fresh
- Manganese-free
Cons
- Costs more per pound than 50 lb stoneware boxes
- Higher shrinkage than No. 46 or B-Mix 5
Who should skip it: potters on a tight budget who will use 50 lb a month. No. 46 is cheaper per pound.
6. AMACO No. 38 White Stoneware: best for cone 10 and large forms
No. 38 is a white stoneware built for strength. AMACO says it has no grog yet holds up for throwing large pieces, slab rolling and hand-building, and that it is "particularly beautiful in wood firings." The white body keeps underglaze color true with little distortion.
The firing range is the catch. AMACO rates it cone 5 to 10 but says it gives best results at cone 10, and the absorption numbers explain why: 7% at cone 5 against 1.4% at cone 10. At cone 5 it is too porous for dependable mugs. Buy it if your kiln or community studio fires to cone 10.
- Cone range: 5 to 10, best at cone 10
- Fired color: white with darker gray specks in oxidation; gray in reduction
- Shrinkage: 13% at cone 5, 15% at cone 10
- Absorption: 7% at cone 5, 1.4% at cone 10
- Size: 50 lb moist box; AP seal
- Price band: about $45 to $60 per 50 lb box at AMACO list price before shipping
Pros
- Strong for big forms
- White body for bright color
- Suits high fire and wood firing
Cons
- Too porous at cone 5 for functional ware
- 15% shrinkage at cone 10
Who should skip it: anyone with a cone 5 or 6 kiln. Choose No. 46 or B-Mix 5.
7. Laguna Frost Porcelain: best cone 6 porcelain
If you want white, glassy-looking work that glows when held to light, you want porcelain. Laguna describes Frost (WC437) as "exceptionally white and translucent" and lists it at cone 6, so it fires in the same kiln as your mid-fire stoneware. Absorption is 0.5% on Laguna's page, the lowest of any clay here except AMACO No. 16 at cone 6.
Porcelain is less forgiving than stoneware. It is softer under your hands, slumps sooner if you over-wet it, and warps more easily in drying and firing. Treat Frost as a second clay once you can center and pull walls reliably. Our porcelain clay guide covers the differences.
- Cone: 6 (Laguna); The Ceramic Shop lists cone 5 to 6
- Fired color: white, translucent when thin
- Shrinkage: 11%
- Absorption: 0.5% (Laguna); The Ceramic Shop lists under 1%
- Price band: about $1.40 per lb at Laguna list price; about $1.50 to $2.50 per lb at dealers depending on quantity
Pros
- Very white and translucent
- Very low absorption at cone 6
- Same kiln as mid-fire stoneware
Cons
- Harder to throw than stoneware
- Prone to warping
- Costs more per pound
Who should skip it: complete beginners and anyone who mostly hand-builds large slabs.
8. AMACO No. 25 White Art Clay: best low fire clay
Low fire clay matures at much lower temperatures than stoneware, which suits small kilns, school kilns and potters who want very bright glaze color. AMACO rates No. 25 from cone 04 to cone 3 and recommends it with AMACO glazes that mature at cone 05. It fires off-white, so colors stay true, and AMACO lists it for wheel throwing, hand-building and modeling.
Because it matures at a low temperature, it shrinks only 6.3% at cone 04, so finished pieces stay closer to the size you made. The trade-off is porosity: 13.7% absorption at cone 04. Functional pieces must be glazed inside to hold liquids, and low fire ware chips more easily than stoneware. See our low fire clay guide for more.
- Cone range: 04 to 3
- Fired color: off-white
- Shrinkage: 6.3% at cone 04
- Absorption: 13.7% at cone 04
- Size: 25 lb and 50 lb boxes; AP seal
- Price band: about $30 to $50 per box at AMACO list price before shipping
Pros
- Fires in small, low-temperature kilns
- Keeps glaze color bright
- Low shrinkage
Cons
- Porous and less durable than stoneware
- Needs a full glaze inside to hold water
Who should skip it: potters with a cone 6 kiln who want tough everyday dishes.
9. Crayola Air-Dry Clay, 25 lb: best option with no kiln
If you have no kiln and no studio nearby, air-dry clay lets you practice pinching, coiling and shaping without firing. Crayola's 25 lb box is a low-cost way to get a lot of clay for kids, classrooms or adults learning to hand-build. Once dry, the listing says it can be painted.
It is not pottery clay. It never becomes ceramic, it cannot go in a kiln, and it is not waterproof or food safe. It also behaves differently on a wheel, which we cover in air-dry clay on a pottery wheel.
- Firing: none; air-dries
- Size: 25 lb, white
- Shrinkage and absorption: not published by the maker
- Price band: budget; check the live price
Pros
- No kiln needed
- Low cost per pound
- Good for learning forms
Cons
- Not waterproof or food safe
- Cannot be glazed and fired
- Teaches little about how real clay dries and fires
Who should skip it: anyone planning to fire work now or soon. Buy a stoneware and keep it sealed until you have kiln access. DAS Air-Hardening Modeling Clay is a smaller alternative for sculpting.
How to choose pottery clay
The wrong clay body leads to leaking mugs, cracked pieces or clay melted onto a kiln shelf. Work through these points in order.
Match the clay's cone to your kiln first
Every clay has a firing range. Fire it below that range and it stays weak and porous. Fire it above and it can bloat, slump or stick to the shelf. Check your kiln's maximum cone, then pick a clay whose best cone sits comfortably below it. Many home electric kilns are rated to cone 6 or higher, which is why cone 5 to 6 clay is the usual default. Orton's chart puts cone 6 at about 2,232°F (1,222°C) at a 108°F per hour finish rate. Our pottery cone chart lists the rest.
| Firing range | Typical cones | Clay types | Example in this guide |
|---|---|---|---|
| Low fire | 06 to 04 | Earthenware, low fire white | AMACO No. 25 |
| Mid-fire | 5 to 6 | Stoneware, cone 6 porcelain | No. 46, B-Mix 5, Frost |
| High fire | 10 | Stoneware, porcelain | AMACO No. 38 |
Do you need a kiln for pottery clay?
Yes, every clay in this guide except the air-dry option needs a kiln. Pottery clay only becomes permanent, water-resistant ceramic when it is fired to its cone; dried but unfired clay softens back to mud in water. You do not have to own the kiln, though. Many community studios, schools and ceramic suppliers fire members' or customers' work for a fee, and they fire to a set cone, so buy the clay they support. If firing is not possible at all, air-dry clay such as Crayola's is the honest substitute, with the limits listed above. Our kilns hub explains when buying your own kiln makes sense.
Can you bake pottery clay in a normal oven?
No. A home oven cannot fire pottery clay: even low fire clay matures around cone 06 to 04, about 1,828°F to 1,945°F (998°C to 1,063°C) on Orton's chart, and stoneware needs cone 5 or higher. Clay "baked" in a kitchen oven only dries out, and it stays fragile and not food safe. Oven-bake polymer clay is a different, plastic-based product and does not work on a pottery wheel. Our pottery oven vs kiln guide covers what an oven can and cannot do.
Stoneware clay for pottery is the safe default
Stoneware is dense at mid-fire, forgiving to throw and strong in use. Earthenware fires lower and stays porous. Porcelain is white and translucent but harder to handle. Start with stoneware unless your kiln or your style points elsewhere. Our guide to the types of pottery clay compares all three, and the stoneware clay page goes deeper.
Read absorption and shrinkage on the spec sheet
For mugs and tableware, look for absorption in the low single digits at the cone you will fire. No. 46 is 1.8% at cone 5; No. 38 is 7% at the same cone, which shows why the cone column matters. Shrinkage tells you how much smaller the piece gets: at 12%, a mug thrown 4 in tall ends up about 3.5 in. Make pieces a little larger than the size you want.
Clay for the pottery wheel versus hand-building
Smooth, plastic clays such as B-Mix 5 throw easily and are kind to your hands. Clays with grog or sand are better for slabs, coils and sculpture because they dry more evenly and resist cracking. If you do both, pick a fine-grog body or an all-rounder such as No. 46. For the best clay for a beginner pottery wheel, avoid porcelain and coarse sculpture bodies until you can center reliably. Our wheel throwing for beginners guide covers the first sessions.
Fired color
White and cream bodies keep glazes and underglazes bright. Buff and speckled bodies give an earthy look and change how glazes read. Dark and red bodies make a strong contrast but can mute light glazes. Test tiles with your own glazes tell you more than any photo.
How much is pottery clay?
Moist stoneware typically lists at about $0.60 to $1.00 per lb at maker prices before shipping in October 2026; porcelain runs about $1.20 to $1.50 per lb at Laguna list price and more at some dealers. A 50 lb box of stoneware usually sits around $40 to $60 before shipping. Shipping is the wild card, because moist clay is heavy, so compare the delivered price per pound. Check the live price before you order. Our how much does clay cost guide breaks the costs down further.
Where to buy pottery clay
You have four main places to buy clay for pottery in the US:
- Local ceramic suppliers: usually the cheapest per pound if you can collect, and staff can tell you which bodies local studios fire.
- Maker stores: AMACO sells direct, and Laguna's online store sells moist clay in 50 lb steps up to 250 lb per order.
- Art retailers and dealers: Blick and pottery dealers carry AMACO, Laguna and Standard bodies, often with delivered pricing.
- Amazon: handy for 5 to 25 lb trial sizes, but the price per pound is usually higher because shipping is built in.
A community studio may also sell clay to members, and it fires to a set cone, so buy the body it supports.
Before you buy clay for pottery online, check two things on the listing: the cone and the clay type. A lot of clay for sale on marketplaces is air-dry or polymer craft clay, which looks similar in photos but cannot be fired. Moist pottery clay should name a cone (such as cone 5 or cone 06) and a maker's body name or code.
Buying pottery clay in bulk
Bulk clay for pottery makes sense once you have settled on one body and know your kiln fires it well. Moist clay keeps for months in sealed bags, so a larger order is not wasted if you store it out of frost and sun. Dealers price by the pound with breaks at higher quantities: The Ceramic Shop's Frost listing, for example, sells in 25 lb steps and lists a lower per-pound price at 250 lb and at 1,000 lb than at 50 lb. Laguna's own store takes 50 to 250 lb per online order and larger orders by phone. A pallet of clay is heavy, so ask the dealer for a delivered quote and whether delivery is curbside or needs a liftgate. If you share a kiln with friends, pooling a pottery clay bulk order can help you reach the next price break. Test a 25 lb box before you commit to hundreds of pounds.
Storing and reclaiming clay
Keep moist clay in its sealed bag, out of frost and direct sun, and it stays workable for months. Trimmings and collapsed pots can be dried, slaked and wedged back into use. Keep bodies apart when you reclaim, because mixing a cone 5 and a cone 10 clay gives you a body with an unknown firing range. Our how to wedge clay guide covers getting reclaim back into shape.
Safety: Laguna's pages carry a California Prop 65 warning for crystalline silica, which is in all pottery clay. Clean up with a damp sponge or mop, never by dry sweeping, and wear a NIOSH-approved respirator when you mix dry clay or sand dry pieces.
