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.
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.

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.
a small tomato tin can (as i didn't have the a casting ring/flash at hand)
Butane torch (stove top would work to)
Crucible (ceramic flower pot would do)
Took about 12 minutes including casting time & to be honest I just can't believe how easy it is! plus I just used two little old cans to hold the clay, so there is a massive amount of room for improvement!
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
I made the pour hole in the center of the negative mold with a skewer and then cut a funnel on the opposite side with a knife, fixing it up where need be.
