Freeze & Fuse is an amazing micro-casting technique, using Bullseye Glass Powders to create small and intricate castings. Use our exciting range of Freeze & Fuse moulds to create three-dimensional objects without complicated firing schedules, in any size kiln. Fused pieces can be used on their own or as components for larger projects. Watch our video guide or see our PDF instructions to get started!

These moulds are made of flexible silicone and cannot be fired in a kiln.

TIP: Make sure you don’t leave your moulds in the freezer overnight, as this will dry the pieces out.
