History of the Delft Clay Method of Casting

The Delft Clay Method of Casting is an idea by Hans Karreman, a goldsmith from Delft. Since the eighties, Hans Karreman has been experimenting with mouldable clay. After several years the Delft Clay Method of Casting originated from this. This method makes it possible to cast jewellery and object in gold, silver and other metals.
The Delft Clay Method of Casting consists of a mould and mouldable Delft clay, in which objects can be cast remarkably sharp and fast. The Delft Clay is reusable and cannot dry out due to its special composition.
