Dolomite and limestone are the third largest components of glass raw materials after silica sand and soda ash. In the production of bottled glass, the most expensive ingredient is soda ash. What is the role of dolomite in glass production? Adding limestone can partially replace soda ash and has virtually no effect. The introduction of magnesium oxide in dolomite can further reduce glass production costs.
Dolomite can also provide calcium oxide in the glass industry, adding soda ash - silica systems to act as a flux. Dolomite can also reduce the aging of glass, prevent chemical corrosion caused by atmospheric or moisture, improve the plasticity of colored glass, and increase the strength of glass.
