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 ...

The raw materials that float glass is made up of are: SiO2 – Silica Sand. Na2O – Sodium Oxide from Soda Ash. MgO – Dolomite. Al2O3 – Feldspar. The above raw materials primarily mixed in batch helps to make clear glass. If certain metal oxides are mixed to this batch they impart colors to the glass giving it a body tint.

Apr 13, 2020 There are four main raw materials used to make glass: silica sand, soda ash, dolomite and limestone. In many cases, broken pieces of glass called cullet are also added to these raw materials to help them properly melt when heated. There are a number of different ways to make glass, depending on the desired finished product.

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. In order to make crystal clear glass, the use of special sand, i.e., silica sand is done. These very fine sand particles come in white color.

The main raw material used to make glass is sand. To make clear glass, a special sand called silica sand is used. This fine white sand is needed because it is very pure and does not contain other unwanted chemicals. It is “washed” to remove as many impurities as possible, as impurities can adversely affect the clarity and color of the glass.
