This is amazing! I can't wait to try it out. I have some questions, maybe someone knows the answers?
How did you make it a complete figure? Cast the other half and then glue? Can you cover it in two halves of silicone? What's a good way to do this?
Can you cast any material, like plaster, fine sement or molten plastic in this?
Is it a good idea to use a bit of Vaseline on the casting object to make it easier to detach or is this simple anyway with silicone?
I will be testing this out tomorrow with this product on a candy mold. It lists on the package that it can come in contact with food. http://t.homedepot.com/p/DAP-2-8-oz-Silicone-Aquarium-Sealant-00688/100128841/
Hi :) I love this instructable. I was wondering if you might know if this method of mold making would be safe to use with cooking. I would like to make some fondant molds but not sure if it is safe to put food stuff on this silicone. Thanks for sharing this project :)
DEFINITELY NOT! I think there is food safe silicone, if you need it.
Is there a limit on the thickness of the mold walls? I know that most tubes of silicone say to not exceed 1/8" thickness. Will this technique permit thicker walls?
Done this today. I'm still waiting for it to set. How long will it set? I did full object (chicken) mold. I'm planning to use clay afterwards for my chickens. Hope it will go all well.*fingers crossed
