Feldspar Ceramics, Glass, Fertilizer: 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 feldsparrich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.

Gabbro is an intrusive igneous rock composed primarily of plagioclase feldspar and large amounts of mafic minerals like pyroxene. It has a phaneritic texture, meaning its interlocking crystals can be seen with the naked eye. It is usually dark gray, black, or dark greenish, and is closely related to basalt.

Feldspar Processing General1 Feldspar consists essentially of aluminum silicates combined with varying percentages of potassium, sodium, and calcium, and it is the most abundant mineral of the igneous rocks. The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O).

The vast majority of the minerals that make up the rocks of Earth's crust are silicate minerals. These include minerals such as quartz, feldspar, mica, amphibole, pyroxene, olivine, and a variety of clay minerals. The building block of all of these minerals is the silica tetrahedron, a combination of four oxygen atoms and one silicon atom.

Rhyolite is a type of igneous rock that is formed from volcanic activity. It is characterized by its high silica content and finegrained texture. Igneous rocks are formed when molten rock, or magma, cools and solidifies. Rhyolite is typically found in volcanic areas and is often associated with explosive eruptions.

Feldspars of importance to ceramics are aluminosilicates of sodium, potassium, and calcium (Jones Berard, 1993) They are used as fluxes to form a glassy phase in bodies, thus promoting vitrification and also serve as a source of alkalis and alumina in glazes. The pure spars are albite (NaAlSi 3 O 8), orthoclase or microcline (KAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8).
