ComposiCast urethane casting resin. The original part, made by Helene Farrar was made with terracotta clay and sealed with a shellac spray.
Since this is a one part mold, the ComposiMold-LT was poured over the fish and allowed to solidify by cooling. A mixture of 1-teaspoon white glue and 1 cup of water was used as the mold release for the casting. For the casting a silicone mold release was used.
