Delft Casting Technique

Delft Casting Technique

Delft Casting is a great way to cast pieces with very little cost and very little equipment. It’s a firm favourite of mine and is very rewarding when it works. Those of you who attended the casting course at The Brewery Arts Centre will know how tricky it can be and it really is a case of practicing to get your success rate up.

Key things I learned using the Delft Casting Technique:

  • Chop the clay up well, to loosen it all
  • Compact the delft clay firmly so that it takes a good impression
  • Don’t forget your release powder in between the two layers
  • Sculpt the pour hole and think of water flowing. Make holes bigger, shape the funnel nicely and reduce all the area of friction that might slow the silver down as it enters the hollow withing the mould
  • Make sure your ring marks on either side of the mould line up!
  • Add plenty of air holes as any trapped air will stop the silver flowing into that part of the shape
  • It takes longer than you think

Andrew Berry, from At The Bench, has a wonderful series on the Delft casting technique:

Remember, when using Delft casting, it is better to have a little more material on the final cast piece of jewellery as it’s easier to remove silver than put it back on if too thin in places.
