Chemical Resistance and Durability: Limestone adds calcium oxide to glass, which enhances its chemical resistance and overall durability, making it suitable for a wide range of applications.

Fluxing Agent: As a fluxing agent, limestone lowers the melting temperature of the glass mixture, facilitating easier shaping and forming of glass objects.

Viscosity Reduction: Limestone reduces the viscosity of molten glass, improving its workability during the forming process.

Prevention of Devitrification: By preventing devitrification, limestone helps avoid clouding and defects that can form during the cooling process, ensuring a clear, high-quality finish.

Transparency Enhancement: Limestone improves the transparency of glass products, making them ideal for optical clarity and aesthetic purposes.

Fiberglass Production: Limestone is used in the production of fiberglass, a specialized type of glass commonly utilized in insulation, automotive parts, and the construction industry.
