Ok, so in order to make more than one at a time, I need to make a mold of my mold so I can make more molds… so I can cast multiple small bird cups in a day. A lot of molds right? Well they are small so really it’s relatively easy. Below you see the silicone molds into which I will cast No. 1 Pottery plaster to create multiple slip molds for casting into. It will all make sense soon, I promise.
