Glass is one of man’s most valuable and versatile materials. Glass is formed from those elements such as silicon, boron, phosphorus and arsenic that can be converted into glass when combined with oxygen, sulphur, tellurium or selenium common glasses contains about 70% SiO2. The term float glass pertains to all glasses produced in a flat form. It is well known fact all over the world that the best quality glass can produce with the help of float glass technology. Glass has varied applications. It is used in windows, structural building blocks, chemical reaction equipments, pumps, piping, vacuum tubes, light bulbs and containers etc. Except these uses, glass can be made for particular use by changing minutely in composition to make things like optical glass, photosensitive glass, enamel glass, ceramic glass etc. Float glass is used for glazing wherever transparency is required in building. It is also a raw material for making safety building primarily for making safety glass, for automotive and other transportation uses. Mirrors and otherwise finished or processed float glass for furniture or interior decorating is also made from it. It is mostly used in building construction, photo frames, automobiles, railways etc. because it is used as a raw material for the manufacturing of safety glass, which is a very consumable product now a days, so its use is increasing day by day. It is expected that the demand of float glass will increase tremendously. New entrepreneurs can well venture in to this field.
