You are in my plans to purchase a vacuum chamber in the future but not yet. I've seen some tutorials on how to build, never tried or even seen the operation of any. But one day ...

Thanks so much for sharing that. Do you go use any kind of vacuum chamber (or some other process) to get the air bubbles out of the silicone before you pour it?

HI! I do not have a vacuum chamber. Use extreme caution when mixing and pouring the silicone. Start with a small amount that covers the part and let drain. then pour the rest into a corner leaving completely fill the mold. This minimizes the bubbles on the surface.

Cool. Where did you get your vacuum chamber? I've seen online where people have converted paint pots from Harbor Freight (if you're familiar with that retail store) Any thoughts on that?
I'm really only looking to make molds of sculptures no larger than 6" high and 6" deep... if that big.
I appreciate the help!

Wow. Amazing gallery. I have a question, do you make molds and castings from your sculptures? If so, would you mind running down your process?

Yes I do! My process is simple. Mold on two parts of silicone rubber. Casting in polyester resin. The number of pieces of sculpture depends on each one and its complexity. The ideal is that each part is simplified to facilitate the removal the casting of the mold. Does that help? More questions, feel comfortable asking.
Thank you!
