I glaze my charms with a water based polyurethane floor finish but sometimes the glaze scratches off and other times it doesn't. I've heard that some people bake their pieces again after they glaze them to keep the glaze from scratching off. I was wondering if floor finish is safe to put in the oven you also bake food in (because of all the chemicals)? I bake in a oven roaster only used for polymer clay but I don't know if even that would keep all the chemicals in.
PLEASE HELP ME!!!
