Feldspars are a group of closely related minerals that together make up the majority of the Earth's crust. All of them have a hardness of 6 on the Mohs scale, so any glassy mineral that's softer than quartz and cannot be scratched with a knife is very likely to be a feldspar.

Feldspar - Uses: 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.

┗ 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. ┗ It is used to make porcelain, sanitary ware, and tableware. ┗ It is used in making mild abrasives, latex foam, and urethane.

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. Each year about 600,000 tons of feldspar is mined in the United States from quarries in South Dakota, Oklahoma, ia, California, North Carolina, and Idaho.

Alkali feldspar (also called potassium feldspar or K-feldspar) has a color range from white to brick-red, and it's typically opaque. Many rocks have both feldspars, like granite. Cases like that are helpful for learning to tell the feldspars apart. The differences can be subtle and confusing.

Potash Feldspar digitalfire. Potassium feldspar melts at around 1200C (higher than soda feldspar) producing a more a viscous melt than does sodium feldspar It can also produce a crystalline phase (leucite) that contributes to opacity Thus in industry potash feldspars are often used more for matte glazes while soda feldspar is used
