The production of container glass, such as bottles and jars, typically requires a specific type of silica sand known as soda-lime silica sand. This type of silica sand is the most common and widely used in the glass manufacturing industry.
Soda-lime silica sand is valued for its availability, cost-effectiveness, and compatibility with the manufacturing processes involved in container glass production. Different glass manufacturers may have slight variations in their specific requirements based on their production processes and desired glass properties.
70-75% SiO2 providing structural integrity as the primary component of glass
Controlled sodium carbonate for lower melting temperature and calcium oxide for chemical resistance
Less than 150 ppm to prevent undesirable greenish tint in container glass
Controlled range for consistent glass quality and proper melting and forming
Minimal alumina titania and other metal oxides for desired clarity
