The Delft Clay Method is a highly refined form of sand casting that substitutes genuine Delft Clay from Holland for ordinary casting sand. Reproduce your original models quickly with this unique Delft™ clay casting system. Keep the traditional techniques of sand casting alive and well with this re-usable, ultra-fine Dutch clay mix.
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. Because this is a type of sand casting, it is best suited to producing castings without pronounced undercuts.
