Feldspar

Feldspars (KAlSi 3O 8 NaAlSi 3O 8 CaAl 2Si 2O 8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks.

Feldspar Distinctions, Characteristics & Identification

Aug 10, 2019 Alkali feldspar (also called potassium feldspar or K-feldspar) has a color range from white to brick-red, and it's typically opaque. Many rocks have both feldspars, like granite. Cases like that are helpful for learning to tell the feldspars apart. The differences can be subtle and confusing.

Feldspar Digitalfire

However actual feldspar powders are made from crushed crystalline rock containing a mixture of aluminum silicates of sodium and potassium (with minor amounts of lithium or calcium). They normally contain 10-15% alkali (K 2 O, Na 2 O) and melt well at medium to high temperatures and are an economic source of flux.
