Ceramic suppliers and studios sell clay in 25 or 50 lb boxes. Shipping clay is heavy, so local pickup often saves money.
Professional insight
Potters pick clay by firing cone first, then color and texture.
- Match the clay cone rating to your glaze cone.
- Grog adds strength for handbuilding but scratches on the wheel.
- Check shrinkage percent if pieces must fit lids.
- Air dry clay cannot be fired in a kiln.

Storage
- Keep bags tightly closed to stop drying.
- Store above freezing; frozen clay can turn crumbly.
- Rewet stiff clay by wrapping it in damp cloth.

Common questions
- Which clay is best for beginners?
- Many start with a smooth mid fire stoneware. Ask your studio first.
- Can I fire clay in a home oven?
- No. Kiln clay needs a kiln. Ovens suit polymer clay only.
- How much clay do I need?
- A 25 lb box makes many small pieces for a beginner.
- Can I mix two clay bodies?
- It can cause cracks. Keep clays with different cones apart.
