Product Details The Delft Clay Method is a highly refined form of sand casting. Delft Clay is much finer than other casting sands such as Petrabond, providing remarkably sharp and highly detailed castings in gold, silver, copper-based alloys, pewter, etc. Castings require very little finishing work due to the fineness of the sand. Once you have cast your piece, the burnt Delft Clay has to be thrown away but the unburnt clay can be re-used. Since this is a cold-moulding process, moulds can be made from patterns composed of wood, wax, epoxy, plastics, and, of course, metal. The delft clay casting system is a type of sand casting, therefore it is best suited to producing castings without pronounced undercuts. This Delft Clay is sold as a 1kg pack.
