Orthoclase, or orthoclase feldspar (endmember formula K Al Si 3 O 8), is an important tectosilicate mineral which forms igneous rock. The name is from the Ancient Greek for "straight fracture," because its two cleavage planes are at right angles to each other.
Alkali feldspar has the formula KAlSi 3 O 8, potassium aluminosilicate.The formula actually is a blend ranging from all sodium (albite) to all potassium (microcline), but albite is also one endpoint in the plagioclase series so we classify it there.
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.
In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase. Glass and ceramics continued to be the major end uses of feldspar.
Custer Feldspar (NaKO.Al2O3.6SiO2 ) is a one of the primary feldspars used in ceramics. It is used in both clay (up to 25%) and glaze (up to ) formulas and is made up of silica and alumina combined with sodium and potassium oxides. Feldspar custer is mined in Custer, South Dakota.

The rocks shown left to right are soda felspar, potash feldspar, nepheline syenite, and Cornwall stone. Feldspars are minerals of varying composition commonly used by potters.
Feldspar is by far the most abundant group of minerals in the earth's crust, forming about 60% of terrestrial rocks. Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspars. Feldspars are primarily used in industrial applications for their alumina and alkali content.
Feldspar Feldspars are the most common minerals at the Earth’s surface. In fact, if the entire composition of the Earth’s crust were regarded as a single mineral, it would calculate out almost exactly as a feldspar.

Stockpile of crude feldspar from MGK Minerals (India) deposit. A soda feldspar cone 4-7. Pure soda feldspar (Minspar 200) fired like-a-glaze at cone 4, 5, 6 and 7 on porcelainous stoneware samples.
Feldspar is by far the most abundant group of minerals in the earth's crust, forming about 60% of terrestrial rocks. Most European deposits offer potassium feldspar as well as sodium feldspar and mixed feldspars. Feldspars are primarily used in industrial applications for their alumina and alkali content.
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.
Adularia: A more ordered low-temperature variety of Orthoclase or partially disordered Microcline.Individual localities should be verified because the adularia structural state is nearly equally represented by microcline and orthoclase specimens.
Feldspar is a common raw 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.
Apr 01, 2016· Almost all porcelain recipes have feldspar in them. A general purpose porcelain recipe has silica, clay and feldspar or nepheline syenite (which is a feldspathiod). A basic common recipe is 25% of each kaolin, ball clay, feldspar and silica. It doesn't really make sense to call something a "feldspar porcelain".
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 …
