Glass manufacturing using lime - Carmeuse

End-use products include container and flat glass. Approximately 90% of the world's glass production is soda-lime glass. Screen-grade limestone is used in glass production as a flux for modifying viscosity, increasing the final product durability and chemical wear resistance. Without limestone, soda-lime glass would dissolve in water.
