Calumite International process and distributes Calumite Slag – a unique,raw material essential for the manufacturing of soda lime silica glass. Slag is a byproduct of making steel.
Calumite Slag offers an environmentally responsible and economically beneficial resource for the glass production industry. This very innovative slag compound increases furnace efficiencies, reduces emissions and energy costs, and improves glass quality.
Calumite Slag can substantially lower glass furnace melting temperatures permitting more glass to be melted at essentially the same temperature when properly formulated into a glass batch. Use of Calumite Slag benefits CO2 reductions, fuel savings and furnace productivities.
