What Beginner & Experienced Potters Are Saying About Our Products

This clay is wonderfully soft and consistent. To be honest, it's so smooth that it seems like synthetic polymer clay, even though it's natural mineral type clay.

Thomas M.

This has been my FAVORITE go to clay as a art teacher for a while now. It holds up in storage very nicely and doesn't dry out at all when needed (I store it wrapped in plastic in mini fridge). Super easy to work with and when pricing against other brands this has more bang for your buck.

Madelaine A.

Old Potters Pottery Clay FAQs

Is air-dry clay good for pottery DIY projects? 

Plus icon Minus icon

Yes, Old Potters Air Dry Clay can be used for a variety of DIY projects. Its smooth texture and pliable consistency help beginner and expert potters easily mold the clay into unique shapes.

What’s the difference between air-dry clay, stoneware, and porcelain clay? 

Plus icon Minus icon

Air-dry clay hardens naturally over time and dries more evenly in a slightly damp or controlled environment, while stoneware and porcelain require kiln firing to fully cure. Air-dry clay is great for beginners and DIY projects, while stoneware clay is valued for its strength and durability, and porcelain for its smooth texture and high-end finish.

Do you ship clay nationwide and internationally?

When you buy clay pottery from Old Potters, your product will be delivered within 5 business days across the United States. We do not currently offer international shipping.

How long does pottery clay take to dry? 

Plus icon Minus icon

Pottery typically takes a few days to over a week to dry completely, depending on the type of clay used and the thickness of each piece.

What is the difference between low-fire and mid-fire clay?

Plus icon Minus icon

Low-fire clays are fired at lower temperatures, meaning they can be done in less sophisticated kilns. Mid-fire clay requires higher temperatures, producing stronger, more durable pieces that are ideal for functional pottery.

Do you offer bulk pricing or school discounts?

Yes, we offer wholesale clay pottery for schools with high-volume orders. Please contact us directly for a customized quote.
