snakeskin casting

I'm getting ready to cast my first snakeskin blanks in Silmar 41. I've done a lot of research on it and think I have a pretty good idea of how to do it. The only thing I don't know about is if I should try to warm the mold before casting. Any advice on the whole casting process with silmar 41...

This is another quick video I shot that explains how I reduce the amount of air bubbles that are typically trapped under the pen tube while in the silicone mold. This application could be used for anything being cast I suppose, but it works great for my snakeskin blanks! All comments...
