• Orthoclase Wikipedia

    Orthoclase, or orthoclase feldspar (endmember formula KAlSi3O8), 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.

    Soda Feldspar. Albite mineral, from which soda feldspar is derived, often tends to be white in appearance compared with the pinkish hue of orthoclase mineral from which potash feldspar is ground. In many cases soda and potash feldspar are interchangeable in glaze recipes.

    The commercial feldspar is orthoclase. The potassium molecule is replaced by sodium to some extent and hence, orthoclase feldspar usually contains a small percentage of sodium. The composition range of the commercial feldspar varies within the limits of potash, soda and upto oligoclase.

    Notes. One of the most important materials for medium and high temperature ceramic glazes. Potash feldspars are often not as pure and white as soda spars. A feldspar is typically referred to as 'potash' if there is significantly more potassium than sodium (typically there will be 2-5% Na 2 O).If the amounts are closer to equal they are termed potash-soda feldspars (or vice versa).

    Potassium feldspar refers to a number of minerals in the feldspar group, and containing potassium: . Orthoclase (endmember formula K Al Si 3 O 8), an important tectosilicate mineral that forms igneous rock; Microcline, chemically the same as orthoclase, but with a different crystalline structure; Sanidine, the high-temperature form of potassium feldspar (K,Na)(Si,Al) 4 O 8

    potassium feldspar orthoclase honeybirdstationery.co.za

    Potassium feldspar melts at around 1200C (higher than soda feldspar) producing a more a viscous melt than does sodium feldspar. It can also produce a crystalline phase (leucite) that contributes to opacity. Thus, in industry, potash feldspars are often used more for matte glazes while soda feldspar is used for glossy glazes.

    Orthoclase: Mineral information, data and localities.

    Although petrologists had used twinning as a method of distinguishing orthoclase from microcline, Wright and Stewart (1958) used the difference in certain d values to calculate a degree of disorder of a sample and thus have a quantitative method to identify the structural state of a potassium feldspar.

    Geologists see feldspar as a mineral and classify feldspars as mainly as albite, microcline, orthoclase and anorthite. However, for use in glazes, we can view feldspars as 'warehouses of oxides' (e.g. because they supply K 2 O, Na 2 O, Al 2 O 3 and SiO 2 to the glaze melt).
