Tata Chemicals is the world's second-largest producer of soda ash, and the glass industry is a major consumer of our product. With manufacturing facilities in India, UK, US and Kenya, TCL is the world's most geographically diversified soda ash company, with an efficient supply chain that can service customers across the globe.

TCL offers a broad range of soda ash grades, in terms of densities and particle size distribution, for various applications. The single largest use of dense soda ash is in the manufacture of glass.

TCL also offers its customers the option of customising its soda ash to suit their requirements for glass in various shapes, sizes and forms: flat glass and mirrors, bottles for beverages and medicines, jars for storing food, insulation materials, bulbs and other lighting, glassware, tableware, float glass, automotive glass, solar panels, TV screens, tubes for televisions and computers, and laboratory ware. The customisation is critical because it determines the properties of the final product.

The soda ash that TCL makes meets the stringent quality requirements of the glass industry. The bulk density of TCL's soda ash ensures uniform blending; the low chloride gives it more furnace life and the lack of lumps guarantees uniform blending, resulting in a negligible loss of soda in the furnace. Dense ash grains smaller than sand grains are preferred. The finer sodium carbonate grain is then capable of distributing more evenly on the surface of silica grains promoting early removal of CO2 before the liquid seals off the voids and channels in the batch.
