How to choose a clay
Four questions narrow our moist clays to a few good matches. The finder above asks the same ones.
- What cone will you fire to? Clay, glaze and kiln all need to match. Low-fire clays mature at cone 06–02, mid-range clays at cone 4–6 and high-fire clays at cone 10. Fired hotter than its range, a clay can slump or bloat. Fired cooler, it stays weak and porous.
- How do you work? Throwing clays are plastic, so they center and pull easily. Many have only fine grog or none. Handbuilding, sculpture and tile clays usually have more grog, which helps thick and flat work dry evenly with less cracking and warping.
- Grog or no grog? Grog is clay that’s already been fired and ground. It adds tooth and strength. Clay without grog is smoother on your hands and takes fine detail.
- Light or dark? Light clays (white, cream, buff) show glaze colors at their brightest. Dark clays (red, brown, black) make glazes look deeper and earthier. Speckled clays add flecks that show through many glazes.
Getting your clay. Every clay comes in 50 lb boxes. Under 1,000 lb, shipping is built into the box price. From 1,000 lb, you pay a lower box price plus shipping, with quantity discounts. Local? Pick up any amount at the lower price.
Common questions
What’s the difference between earthenware, stoneware and porcelain?
Earthenware fires at low temperatures and stays slightly porous. Stoneware fires hotter into a dense, strong body. Porcelain is white and very smooth and can be translucent where thin, but it’s less forgiving to throw.
What clay is best for beginners?
A cone 6 stoneware. Choose one with some grog for handbuilding, or a smoother one for the wheel. Then match your glazes and kiln to cone 6.
Can I fire a cone 6 clay to cone 10?
No. Fired past its range, it can slump, warp or bloat. A cone 10 clay fired to cone 6 won’t fully mature, so it stays more porous.
Can you mix a custom clay?
Yes. We mix custom clay bodies to your formula here in Sheffield, and we also offer a clay reclaim service.
