1.5lbs Delft Clay Casting Gold Silver Copper-Based alloys, Pewter

The delft clay method is a highly refined form of sand casting that substitutes genuine delft clay from holland for ordinary casting sand. The process was invented by Hans Karreman, a Dutch goldsmith. Delft clay is much finer than casting sand, providing remarkably sharp and highly detailed castings in gold, silver, copper-based alloys, pewter etc. Castings require very little finishing work. Once you have cast your piece, the delft clay can be re-used. Since this is a cold-molding process, molds can be made from patterns composed of wood, wax, epoxy, plastics and of course, metal.
