Feldspar Processing In Glassmaking :

FELDSPAR - Ashok Mineral Enterprises

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

Feldspar Millers Base Minerals African Pegmatite

Potassium feldspar is commonly used as a flux in glassmaking and ceramics. Flux is a material that’s added to a solid to lower the solid’s melting point. The flux is a vital component of most glass and ceramic production because it helps control the viscosity of the glass and helps create a glassy phase in ceramics at low temperatures.
