Feldspar in Glass Production - Feldspar from The Quartz Corp Feldspar is commonly used to produce glass with excellent optical properties and strength for industrial and chemical applications. The QUARTZ Corp adheres to strict quality procedures and consistent specifications to ensure that our products perform to our customers’ high standards.
Feldspar is a common material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion.
Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics. The feldspar-rich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.
Glass: Feldspar is an important ingredient in the manufacture of glass and an important material as well, because it acts as a fluxing agent, reducing the melting temperature of quartz and helping to control the viscosity of glass.
Uses of Feldspar Feldspar is extracted from rocks and crushed into fine powder or granules that are used in the manufacturing of ceramic tile, plate glass, pottery, paint, plastics, and fiberglass insulation.
Uses of Feldspar ┗ Feldspar contains alumina, which results in an increase in the strength of the manufactured product. Therefore, this mineral is used in glass-making. ┗ It is used as a filler agent for plastic, rubber, and paint.
