1” or 2” Moon Phase Inserts. 2” Version pictured here.

Silicone inserts can be used in normal silicone molds or our modular molds to created negative space within your casting. As long as they are clean then a small bit of pressure as you place them is all it takes to keep them from moving.

Our silicone inserts match the shapes of their parent molds so you can use these inserts to create a negative in your cast, remove the insert and place in a resin casts from any of the parent molds.

Amy from Alv Art Studio utilizes this method heavily and creates beautiful works of art. Check out some of her work here to see more examples of these in use.
