Mar 03, 2011· Potash feldspar is a naturally accruing compound that has a Potash salt in it. If you need a potash feldspar get it from a ceramic supplier. I don't know of any other places for that product, although there may be some. If you want to experiment the gardening potash try it in glazes test and clay test.

The sulfides, mica, and feldspar were floated in turn and produced a potash feldspar containing the following, in percent: K2O, Na2O, CaO, Al2O3, and SiO2. Sample NMA Petrographic analysis of sample NMA showed that dark minerals were locked with feldspar .
The real potash feldspars also have small amounts of CaO, MgO, Fe 2 O 3, etc. 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.

JACerS is a leading source for topquality basic science research and modeling spanning the diverse field of ceramic and glass materials science.
Although potash feldspar actually begins its dissolve at a lower temperature than soda feldspar, once the melt begins, the formation of Lucite crystals causes a slower and more viscous flow. To know more detail on the products and its quantity as well as Potash feldspar suppliers detail contact us.
Apr 22, 2009· Feldspar Characteristics in a Glaze In glazes, feldspars act as a flux above cone 6 and bring other glaze materials into a melt. By themselves, they form a white, semiopaque glass containing many bubbles suspended in the glaze layer. Feldspar glazes also exhibit high surface tension when vitreous, much like water beading up on a glass tabletop.
offers 865 potash feldspar products. About 24% of these are other nonmetallic mineral deposit, 16% are other nonmetallic minerals products, and 14% are ceramics. A wide variety of potash feldspar options are available to you, such as free samples.

Soda feldspar is a clean white mineral with a melting range of C. Soda and Potash feldspar are interchangeable in glaze recipes but there are some differences between them. Soda feldspar melts better than the potash feldspar. Soda feldspar has a higher coefficient than the potash.
Apr 07, 2015· Most abundant elements on feldspar (in order): Oxygen; Silicon; Aluminum; Calcium, Sodium or Potassium (depending on variety) The exceptions are that Feldspars don't have any iron, magnesium, titanium and hydrogen. When a magma with the average crustal composition cools, the first minerals to crystalize are the ones with the higher melting point.
Textural evidence, supported by published experimental evidence, suggests that the garnet, cordierite, and Kfeldspar are peritectic phases resulting from incongruent melting of the pelitic fraction of the Meguma metasedimentary country rocks.
