Abstract
A novel alkaline earth metal carbonate product for use as a raw material in the glass manufacturing process is disclosed. The alkaline earth metal carbonate becomes a part of the liquid phase in the glass furnace more readily and at a lower temperature; it decomposes to release carbon dioxide gas more rapidly so that all of the gas can escape from the molten glass more easily. Using these alkaline earth metal carbonate compositions, the production capacity of a glass furnace is increased.
