How Windshield Glass is Made. The materials used to create a windshield have several important properties. Obviously, the glass needs to retain its clarity over a long period of time. It also needs to be constructed of strong materials that will provide structural support to the roof of the vehicle in the event of a rollover collision.
In making sheet glass it is customary to use 6 percent of lime and 4 percent of magnesia (magnesium oxide, or MgO), and in bottle glass about 2 percent alumina (aluminum oxide, or Al 2 O 3) is often present. Other materials are also added, some being put in to assist in refining the glass (i.e., to remove the bubbles left behind in the melting ...
Glass is used in the making of different products such as mirrors, storage containers, cutlery items, doors, and windows, etc. The prime raw material that is being used for the manufacturing of glass is sand.
