PLA blue 5kg

Blue earthenware clay. Its blue colour in oxidising atmosphere is a highlight in the range of low firing colours. Its fineness and plasticity make it an excellent choice for wheel- throwing and modelling. Very good behaviour with standard pottery glazes. Available in extruded body (moist form).
