Standard Ceramics #240 White Clay
Standard Ceramics (also known as Standard Clay) is a well-known distributor stocking dozens of clay types but this is one of the brand's better options for wheel throwing. This particular product is white stoneware clay with a high plasticity. It’s a high-fire clay body meant to be fired at Cone 6 and includes a fire clay blend to improve the overall texture.
Like other high fire clays, it has a high shrinkage rate so you’ll need to adjust to avoid damage during the drying or firing process. The company's distributors are limited to the eastern United States and a few international suppliers so this particular clay may be more difficult to find.
