How is glass made from sand?

Trending How is glass made from sand? Glass is used in many things such as windows in your home, bottles and glasses. But are you aware that glass is actually made from sand? Yes, the most important thing for making glass is sand that contains silica. Apart from this, soda ash and limestone are also used to make glass. To make glass, sand is melted in special furnaces at a temperature of around 1700 degrees Celsius. At this temperature the silicon dioxide present in the sand melts and the sand becomes liquid. Soda ash is also added to the sand, which helps to melt the glass quickly. At the same time, limestone provides strength to it, so that the objects made from it are strong. After the sand is properly melted, it is given the required shape through various processes such as drifting, casting and glass blowing. Once the glass is properly shaped, it is slowly cooled in a special oven so that it does not crack. To make colored glass, oxides of different metals are added to liquid glass to give it color. For example, purple color is obtained from manganese oxide, similarly other colors are also given. Today, glass has become an important part of our everyday life in the form of windows, mirrors, bottles, tableware, mobile screens and glasses. Click here for more stories of life and style Click here
