Calcium oxide (quicklime) and calcium carbonate (limestone) products are used in glass manufacturing applications. Silica sand, soda ash and calcium limestone or dolomitic limestone represent together a majority of the raw materials used in the production of glass. Glass is obtained by the fusion of several inorganic substances. Calcium materials are an important component as they render the glass more insoluble which improves the mechanical properties and physical appearance of the glass. Calcium oxide and calcium carbonate remain the lowest cost fluxing materials for glass manufacturers.
Mississippi Lime’s CalCarb® R1 calcium carbonate is a high quality, low iron material with a homogeneous particle size used in glass manufacturing applications. The material quality makes it the preferred calcium carbonate to be used in flint (clear) glass production.
Mississippi Lime’s Pulverized Quicklime and Pulverized Quicklime-FloTreat allow for improved performance as compared to calcined materials. The quicklime products are used to improve energy utilization, effective capacity, material quality and furnace operation.
