Delft Clay Casting Kit

Current Stock:

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 metal. Because this is a type of sand casting, it is best suited to produce castings without pronounced undercuts. 

The Delft Clay Casting Kit includes 4.4 lbs of Delft clay, a 60mm aluminum ring frame, and detailed instructions.
