There are two types of feldspar:Soda peldspar(7 percent or higher Na2O) and Potash feldspar(8 percent or K2O).Feldspar- silica mixtures can occur naturally, such as in sand deposits, or can be obtaied from flotation of mined and crushed rock.
A potash feldspar used in clay bodies and glazes as a flux. Used in porcelain and white clay bodies due to its white firing characteristics. Generally the flux to use if a recipe just calls for a "feldspar". Mined in Custer, SD. WARNING: Contains free crystalline silica, which could lead to silicosis or other lung diseases after very long exposure.
(b) basic feldspars, labradorite and anorthite, with 43% to 53% silica (characteristics of basic rocks, such as diabase, diorite, etc. In commercial quantity and condition, feldspar is found mostly in pegmatite dikes (coarsely crystalline granite). It must be free from black mica, hornblende, tourmaline, and other dark minerals.

Feldspar is the name given to a group of minerals distinguished by the presence of alumina and silica (SiO 2) in their chemistry. This group includes aluminum silicates of soda, potassium, or lime. It is the single most abundant mineral group on Earth.
The sulfides, mica, and feldspar were floated in turn and produced a potash feldspar containing the following, in percent: 9.9 K2O, 0.73 Na2O, 0.97 CaO, 24.6 Al2O3 , and 61.0 SiO2. Sample NMA Petrographic analysis of sample NMA showed that dark minerals were locked with feldspar and quartz grains.

There are many kinds of feldspars, but in ceramics soda, potash and lime feldspars are the most common. Porcelains can contain up to 50% feldspar, stoneware bodies around 15%. Feldspar sources K2O and Na2O to glazes, these can produce very brilliant results. However, the high KNaO produces a high thermal expansion which in turn produces …

Potash feldspars can usually substitute for each other in most glaze formulas without producing major changes in surface, provided the silica and alumina content are not too different. The difference in the feldspars’ silica content can be compensated for by adding or removing silica from the glaze formula.
