Feldspar - Wikipedia

OverviewProduction and usesEtymologyCompositionsWeatheringImagesSee alsoFurther reading

About 20 million tonnes of feldspar were produced in 2010, mostly by three countries: Italy (4.7 Mt), Turkey (4.5 Mt), and China (2 Mt). 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. In ceramics, the alkalis in feldspar (calcium oxide, pota

Whiteware pottery Britannica

Raw materials: clay, flint, and feldspar. Whitewares are often referred to as triaxial bodies, owing to the three mineral types—clay, silica, and feldspar—consistently found in their makeup. Clay is the plastic component, giving shaping abilities to the unfired product and also serving as a glass former during firing.

Feldspar: The Potter’s Pet Rock - Ceramic Arts Network

Dec 22, 2009  Feldspars are minerals of varying composition commonly used by potters. Feldspars form a glassy, white surface when fired high enough. They have a very long range, they begin melting at cone 4 and continue fusing beyond cone 10. They also tend to stiffen a glaze due to their high alumina content. In ceramics there are two basic categories of feldspars: potash feldspars, in which the primary ...

Orthoclase - Wikipedia

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. It is a type of potassium feldspar, also known as K-feldspar.The gem known as moonstone (see below) is largely composed of orthoclase.
