Improvements in the manufacture of glass-ceramic materials

A glass composition to give a light coloured glass-ceramic consists essentially of, in weight per cent, SiO2 40-60, Al2\O3 5-15, CaO 25-35, Na2\O 0.5-5, F 0-3.7 and ZnO 1.5-3. The glass is made by melting a batch consisting of a blast furnace slag 51-54 wt. per cent, sand 29-33%, ZnO 2-3%, Na2\SO4 5...
