ok, I suppose I could surf the internet and get my answers, but I know there is much talent on this forum and I wish to find out if any of you can answer my questions regarding smelting...since my nephew moved in with me, I am trying to expand his horizons and I wish to learn new things as well......and he is interested in metal working.......we will be taking classes together soon.........so we are about to build a small foundry. my question is this........I have a fiberglass piece I wish to cover with aluminum.......is that possible or will the heat melt the figerglass? anyone?
