Glass is one of man's most valuable and versatile materials. About 700 different compositions are in thousands use. These are fabricated into tens of thousands of different articles that have combinations of properties for about a thousand essentially different uses. Glass is formed from those elements such as silicon, boron, phosphorous and arsenic that can be converted into glass when combined with oxygen, sulphur, tellurium or selenium. A common glass contains about 70% SiO2. Sodium carbonate or soda ash decomposes, to sodium oxides as the batch of raw material melts. Consequently it acts as a flux. The carbon dioxide given off helps to stir the batch, and the oxide lowers the melting point (and the viscosity of the formed glass at any given temperature). Flat glass industry has developed world wide since the float glass process started in the 1980s. It is well known fact all over the world that the best quality glass can be produced with the help of the float glass technology. There are no waves and distortion in the sheet glass manufacturing with the help of float glass technology, is the final product is free of all defects. The float glass sector is having a rapid development on production process, product yield, variety and above all quality. Currently float glass production has accounted for more than 70% of total output. However, at the same time of bolting the vertical upwards process, and developing float glass, the market contradictions of the demand for thin glass have also emerged. The industrial structure of the glass sector in India has been optimized continuously. Diversified new technologies and new products have been developed and glass-processing technology is developing rapidly. In the past, flat glass was used as a transparent material only, but now a days, its multiple functions have been opened out, such as light control, thermal regulation, energy saving, noise control, decoration and environment beautification. The total float glass manufactured in India is approximately 1million tons per annum and almost 77 per cent are consumed domestically. The demand for the float glass, barring the economic slowdown in 2008-09, is increased at a CAGR of 15-20 per cent during the last 2-3 years against the global growth rate around 4 per cent. The total size of the net float glass industry is around 4000 tonnes a day and around 67 percent constitutes clear float glass. Currently, the float glass industry is growing at a healthy rate of 18 percent buoyed by demand for both architectural and automotive glass. There is a huge market for float glass in the country resulting from the growing realty and auto sectors. Also, the extremely low per capita consumption of only 0.7 kg in India as compared to average of 8-10 kg in other developing economies is a tremendous potential for growth of this industry. The glass industry is rapidly transforming. There is a very good scope for new entrepreneurs to venture into this field.
