This is a traditional red earthenware clay body. It is very popular for its fineness and excellent plasticity. Its coefficients of thermal expansion are ideal for standard pottery glazes, in both single and twice firing processes. Incredible results in reducing atmosphere can be obtained (metallic reflection technique).This clay is suitable for both wheel-throwing and hand building.

This clay body is widely used and very popular in Europe.
