Application Of Limestone In Glass Manufacturing

Day 29/01/2021

Limestone (Calcium Carbonate) is one of the main components in glass manufacturing. Its’ main function is to introduce Calcium Oxide into glass recipe which is needed to improve chemical resistance and durability. It also acts as flux in glass manufacturing.

Glass industry required high limestone (CaCO3: 94.5%) combined CaCO3 and MgCO3 should be 97.5%. Iron and other colouring matter like carbon are regarded as objectionable. Fe2O3 should be up to 0.20% (max.). For colourless glass, limestone should not be more than 0.04%; and for bottle glass Fe2O3 up to 0.05% is used.

           

SHC Group is one of leading exporter on limestone lump in Vietnam. Our limestone is ideal for the glass industry as it has a high purity with very low levels of undesirables and contaminants that would be detrimental to the glass making process. It has a very low Iron content typically < 0.03% Fe2O3 with high Calcium content in the order of 98.5% CaCO3 and with the added advantage of consistent Magnesium content typically of 1% MgCO3. The Limestone that is produced can have both economic and environmental benefits to the glass producer.
