It's hard to imagine if modern people nowadays doesn't get contact with glass. Almost every modern equipment use glass as its primary material. Lamps, for example, use glass to avoid direct contact with human being. Television uses glass for its screen. Since glass has such an important role in our life. We need to know what glass really is and how it created.

It is widely known in public that glass is mixture of three ingredients: Sand or silicon oxide which is the most important elements to make glass, soda (Na2CO3) which helps to lessen the process temperature from 2000^oC to 1000^oC, and limestone so that the mixture doesn’t dissolve easily.

After collecting these three components, we combine them in a furnace and melt it at 1000^oC or more. As soon as the mixture melts, we pass it into two tunnels. One of them pours it into an empty container that has been designated to form several kinds of bottle. In this container, a flow of air is run into it in order to cool down the hot mixture.

The other tunnel leads to a roller machine that justifies the molten mixture so that the glass is produced in a plate form. These plate form then utilize in many way such as, in a building, television, light bulbs, and other products.
