Here are the basic components of modern glass: . Pure Silica (SiO2, fused quartz) represents 70-74% weight of modern glass. In ancient times, glassworkers prepared recipes with more than 90% of pure silica, but because this substance has a melting point of about 2000 degrees centigrade (3,600° F) chemist found a way to lower that temperature by introducing various additives into the mix ...

Feldspar comprises of group of minerals distinguished by the presence of Alumina and Silica in their chemistry. Glass and Ceramic industries use Feldspar as flux, a flux is a material that lowers the melting temperature of another material, in this case, Glass. It is also used as an extender and filler in production of variety of products.

3.2 These test methods do not preclude the use of other methods that yield results within permissible variations. In any case, the analyst should verify the procedure and technique used by means of a National Institute of Standards and Technology (NIST) standard reference material or other similar material of known composition having a component comparable with that of the material under test.

In glassmaking feldspar is used a source of Al 2 O 3, Na 2 O, and/or K 2), and SiO 2 [borosilicate glass; soda-lime glass; fiberglass; TV tube glass]. The alumina enhances the workability of molten glass, increases the resistance of glass to chemical corrosion, improves the hardness and durability, and inhibits devitrification,

The development of the float glass manufacturing method revolutionised the building glass industry. Today float glass is used for clear glass and it is used to make many other specialist products. Glass and Glazing in 21st Century Buildings Small window panes and a …

1. One of the purposes: glass flux. The iron contained in feldspar is relatively low, easy melting than alumina, relatively speaking, K-feldspar melting temperature is low and broad category, it is often used to increase the glass batch alumina content, thereby reduce the amount of alkali in the manufacturing process of glass. 2.
