I recently purchased the butterfly and flower molds that everyone was raving about. After reading the thread on that I was wondering if the same principles would apply to silicone molds? In particular the jewel molds. Or would this technique work with any plastic mold?

If anyone has advice on using gelatin for this purpose I would appreciate it. Thank you!

I think the mold has to be fairly flat for it to work.

I tried it, the gelatin doesn't dry like a gem (like molten sugar or iceomelt does) it looses it's shape when drying. It shrinks - for lack of a better description.

Thank you for replying! It was an idea, back to the drawing board.

You ever seen those clear christmas ornament balls in the craft store that come apart so you can fill the middle? I painted gelatin on the inside to see if I could make a ball shape and it dried funny. However, when I painted it on the OUTSIDE it kind of helped it hold it's shape until it finally dried and popped off. Can you paint it on the outside of the gem shape? It might work?

It would be worth a try, we'll see! Thanks for the idea......
