SIO-2® PM Black Earthenware Low Fire Ceramic Clay Body, 4 lb Sample
Black manganese earthenware clay. Its black colour in oxidising atmosphere is a highlight in the range of low firing colours. Its fineness and plasticity make it an excellent choice for throwing and modelling. Very good behaviour with standard pottery glazes. Available in a convenient 4 lb package for smaller projects, or to test and see if this is the right clay for you.
