Aluminum Ring Frame, and detailed instructions. Download the attached Delft Clay instructions for complete step-by-step instructions on the Delft Clay Method. Delft Clay is imported from the Netherlands; aluminum ring frames are made in USA. Instructions: 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.
