ABSTRACT:
A process for using shredded scrap or virgin fiber glass in combination with starch, water and other components to make ceiling tiles. The tiles are made by initially preparing a mixture of water, starch, boric acid and fire clay. That initial mixture is then heated to form a gel. Fiber glass is then added to the gel to form a pulp. The pulp is fed into trays to form slabs. The slabs are dried and finished into tiles.
