I use plaster as a basic material to build many terrain pieces. I cast my plaster in RTV silicone molds. I own many molds of the Castlemolds serie (Hirst Arts Fantasy Architecture). I also made many custom mold using different RTV silicones. I found from my trials that the best ones for my uses are manufactured by GE Silicones. Here’s a shot of one batch of castings from this afternoon. I’m still working on my 15 mm WWII buidlings. I also cast a few more of my custom Settlers of Catan 3D tiles. I have enough tiles ready for a basic game but I will need more for an advanced board setup! (More is always good!).
