I like making molds in silicon for casting with hot glue because it will not stick. I am not sure what would be best for hot glue though.
If you could find a good polishing wax, that might be better. The harder the better as it will take more heat to melt it. If the wax melts, if will go inisde the hot glue and discolor it as well.
