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).

A new spodumenerich pegmatite was recently discovered on the north side of Plumbago Mountain, Oxford County, Western Maine. The site is about km northwest of the famous Dunton gem tourmaline pegmatite. It is an albitequartzspodumene pegmatite containing gigantic crystals of spodumene and montebrasite. Some spodumene crystals are more than 11 m in length. The upper portions of the ...

Moonstone is a variety of the feldspargroup mineral orthoclase. It's composed of two feldspar minerals, orthoclase and albite. At first, the two minerals are intermingled. Then, as the newly formed mineral cools, the intergrown orthoclase and albite separate into stacked, alternating layers.

Orthoclase is a feldspar mineral with a chemical composition of KAlSi 3 O 8. It is one of the most abundant rockforming minerals of the continental crust. Orthoclase is most widely known as the pink feldspar found in many granites and as the mineral assigned a hardness of "6" in the Mohs hardness scale. ADVERTISEMENT.

A major difference between Kspar and plagioclase are the appearance of markings on the cleavage faces. Plagioclase feldspars will typically show tiny grooves, or striations on one cleavage face (Figure, left). Potassium feldspar will exhibit exsolution lamellae, wavy lines look like wood grain, instead of striations (Figure, right).

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.
