Can I use resin without hardener?

On their own, epoxy resins are very stable fluids with relatively long shelf lives. It is only when mixed with an epoxy hardener that they can cure properly.

Can you reheat resin?

You probably can’t. If it’s a thermosetting polymer, which is generally what is meant by “resin”, these simply don’t melt. Rather than melt, these networks will break down with heat, especially in the presence of oxygen, forming different molecules to the precursors used to make them.

Why is my resin not clear?

Foggy resin projects can happen for a few reasons: Make sure the mold is clean and completely dry before pouring. The mold can play a part in the finish. If the surface of your mold is shiny, the resin will be shiny. This silicone mold is very matte, therefore the resin turned out dull and matte.
