Description

Conveniently comes filmed-wrapped in a 27.6 lb. (12.5 kg) package

Black earthenware clay body. Its black color in oxidizing atmosphere is a highlight in the range of low firing colors. Its fineness and plasticity make it an excellent choice for throwing and modelling. Very good behavior with standard pottery glazes.

Available in extruded body (moist form), being suitable for wheel-throwing, shaping and modeling.
