Product Description
Uses
Feldspar is used to make dinnerware and bathroom and building
tiles. In ceramics and glass production, feldspar is used as a
flux. A flux is a material that lowers the melting temperature of
another material, in this case, glass.
Substitutes and Alternative Sources
Feldspar can be replaced by other minerals and mineral mixtures of
similar physical properties. Minerals that could be used to replace
feldspar include clays, talc, and feldspar-silica (quartz)
mixtures. The abundance of feldspar will make these substitutions
unnecessary for the foreseeable future.
Background
Feldspar is the mineral name given to a group of minerals
distinguished by the presence of aluminum (Al) and the silica ion
(SiO4) in their chemistry. This group includes aluminum silicates
of soda (sodium oxide), potassium (potassium oxide), or lime
(calcium oxide). Feldspar is the single most abundant mineral group
on Earth. Together, the varieties of feldspar account for one half
of the Earths crust. The minerals included in this group are
orthoclase, microcline, and the plagioclase feldspars. They form in
a variety of thermal environments, during the crystallization of
liquid rock (magma), by metamorphism of rocks deep in the earth,
and in sedimentary processes.
Feldspars are relatively hard at 6 on Moths' hardness scale.
Feldspars are generally light-colored, including white, pink, tan,
green, or gray. The color varies due to impurities within the
crystal structure. Feldspar is the mineral that gives granite its
pink, green or gray color.
When feldspar weathers from igneous or metamorphic rocks, it can
accumulate as sand. It is, however, easily weathered, and
eventually will break down into clay.
