PROCESS FOR MANUFACTURE OF FLAT GLASS ON A MOLTEN METAL BATH

摘要

In a process for the manufacture of flat glass which comprises flowing molten glass onto a molten metal bath and advancing the molten glass on the bath in ribbon form, the improvement residing in that the molten metal is contacted with a refractory of acidic or neutral oxide or low alkali or nonalkali glass which is replaceably immersed in the molten metal bath, and that the refractory or low alkali or nonalkali glass on which the reaction product thereof with the alkali metal oxide in the molten metal is formed is withdrawn from the bath to be replaced by new refractory or glass at regular intervals.
