Sodium Silicate Glass (Lumps/Cullet)
Furnace Process: Silicon dioxide (silica sand) is fused with sodium carbonate (soda ash) in a furnace. This process allows for ratios of silica (SiO₂) to Na₂O from 2.0 to 3.4. Glass briquettes (also called lumps) are produced, which can be sold.
We have an in-house lab for testing all the parameters, including purity and impurity. All our products are approved, and we are an ISO 9001 2015 company and NABL Certified Laboratory.
