Delft Clay works a lot like sand casting does, however allows finer details in the cast and with the aid of the metal flask rings it makes the casting process enjoyable and fairly easy, even for a beginner.
You can buy the full Delft Clay Casting Kit from amazon.
What is Delft Clay?The Delft Clay method of casting is a form of sand casting. It makes it possible to make remarkably sharp castings of many objects in gold, silver and other metals. After casting, the Delft clay can be re-used immediately.
Cast objects are very detailed and hardly distinguishable from the original model after the casting, the clay 1 mm around the cast is burned and has to be removed. The rest of the clay can be re-used immediately.

How to casting with Delft clay using pewter!This was my very first attempt at casting using Delft Clay, it was very very easy and worked perfectly frist time! Pewter is a great starter metal to cast in as it has a low melting point and doesn't burn the clay.
- Delftclay or Petrobond Sand could be used.
- a unwanted pewter mug (for the metal) or you can buy from amazon
- a old key
- a small tomato tin can (as i didn't have the a casting ring/flash at hand)
- talcum powder
- Butane torch (stove top would work to)
- Crucible (ceramic flower pot would do)
First i cut the tin can in half and packed both half’s tightly with Delft Clay.
I then lightly dusted the blank molds with talcum powder, to make it easy to separate the key and the molds from each other.
Then I pressed half the key into one side of the clay mold (in the center and then placed the other half of the mold on top and pressed firmly and then marked, on both halves of the of can a reference line so I can recenter it when casting.
then gently as possible I pulled the molds apart and removed the key, leaving my negative mold on both sides
Then put the mold together and lined up the center marks. placing it down carefully on the table with the pour hole facing upwards.
After putting on my safety gear I Melted the pewter in my crucible and while still applying heat i slowly move the crucible to my mold and I one quick wrist action, I poured it in, then waited for it to cool.
The Finished Result! could be cleaned up a lot nicer however.

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.
