Casting The Lion

St. Mark Silicone Mold

Back at school now I’ve begun the process of casting St. Mark, The Winged-Lion. St. Mark is an original alabaster carving I finished in the spring of 2007. I’m so found of the piece that I’ve decided to try my hand at reproducing it. Now having a little bit more experience with casting and mold making, I’m fairly confident that I can pull off the task.
I’ve started with a RTV-silicone rubber mold. Four coats is all that’s needed to create a strong, stretchy skin. The silicone should work much nicer than polyurethane; it has greater flexibility, and a longer library life, and requires no release agents.
The next step shall be the jacket mold.
