In the last blog post, we went over step by step how to make the brushable silicone glove mold. In this post, we will cover step by step how to create the mother mold which is the rigid outer shell that helps support the mold during casting. I will be creating this mother mold from water activated plaster impregnated gauze strips. These plaster strips can be purchased at most art and hobby stores, like Michael’s.There are other ways and materials to create mother molds, but I find this way easy and simple for beginners and for small to medium sized projects.
Your work area
That’s it! You should now have a brushable silicone mold and a functional mother mold to support it when casting! When it is time to cast, you can keep the halves of the mother mold together with tape or clips. In our next blog post, I’ll go over how to use this mold to create a cold cast bronze piece.
