Thanks for a great tutorial. I would recommend putting some cornstarch in the bowl and then the silicone, and continue by layering the ingredients for an easy mixing. Good Luck.

I want to try this. Thanks for sharing. Where do I get this liquid plastic? Did not see link. Hope it is not expensive.

What would make my mixture turn rubbery before I get through casting?

I just wanted to know if the DYI silicone molds were any good to do resin casting. If anyone knows, please let me know. Thanks so much
