ABSTRACT:
The present invention relates to a process for forming glass-ceramic tiles. Spent aluminum potliner containing carbonaceous material, fluorine, and glass forming materials is oxidized under conditions effective to combust the carbonaceous material and volatilize partially the fluorine in the glass forming materials. The oxidized glass forming materials are vitrified to form a glass melt. This glass melt is then formed into tiles containing fluorine.
