A Paper Review on Glass Processing

Glass has change the world more than any other material. This seminar deals with the glass processing and some different types of glasses and their applications. As we know that glass is transparent silica product which may be amorphous or crystalline depending upon the heat treatment. To manufacture it, a mixture of silica and other oxides are melted and then cooled to a rigid condition. Glass does not change from a liquid to a solid at a fixed temperature but remains in a vitreous noncrystalline state. In this seminar we will look at the main methods used for processing of glass products glass processing could be said to be the most important processing method for glass. We will also look at processes that are used to modify glasses for specific applications .Glass production starts with a mixture of raw materials which for glass manufacture often contain a high proportion of naturally occurring minerals.(e.g. sand and lime stone) to the final packaging. The major steps involve in the processing of glass are batch preparation, melting and refining, forming and shaping, thermal conditioning, annealing, finishing, cutting and inspection etc. Glass processing deals with the different stages of glass manufacturing such which type of raw materials are required for batch preparation then how melting takes place and also which type of forming process are carried out. After these whole process glass is drawn off for further cutting and inspection process after all these processes glass is obtained in required size and shape.
