Polyform Clay, 2 lbs.
Polyform clay is used to sculpt an original form to make castings from. The main advantage that Polyform Clay has over other types of clay is that it does not break down in the heat generated by the curing investment. This means that there is a minimum of sticking with no residue to burnout. It is a smooth, easy working clay that can be 'heat cured' for the production of multiple images. Sold in 2 pound blocks. This product is not for use in the kiln but for making plaster castings.
