  • Made of soft silicone
  • No release agent is needed
  • These moulds will work with metal clay and polymer clay

Rememer that metal clay will shrink! Check the packaging for the brand you use to see the percentage.

ie. a 10mm mould with metal clay that shrinks at 12% will product a fired metal piece that’s approx. 8.8mm.

The plaster impression is made with museum grade fine plaster of paris and is made using the exact mould it comes with. So you are guaranteed a perfect match!

If impressions are not seen as an option on the product page, they are not available for that product at the moment.
