Casting With Hot Glue ?

Casting with Hot Glue Stick

I had some small silicone molds done yesterday and have no casting resin on hand. I have some plaster but it would be too heavy. So Im curious what else people use to make some emergency castings. Apparently, the answer is hot glue stick ! I have lot’s of it and why not ! It turn out okay. Doesn’t stick to the silicone mold at all even without any mold release.

Main problem with this method is air bubbles. I tried to do it as slow and careful as possible, still get some minor bubbles on the surface. Other than that, its awesome. Can be shaped when it still slightly soft or just use a lighter to make any adjustment and stick it to your project.
