Potassium occurs abundantly in nature such as in seawater, certain clays and rock-forming minerals. The seawater is a source of potassium that contains around 380 mg/L, which constitutes approximately 1.1% of the total salt present [].It has been estimated that the total oceanic abundance of potassium is around 5.10 × 10 14 tons while the …

Sustainable Process for the Extraction of Potassium from Feldspar …
To recover potassium from feldspar, a biowaste, i.e., eggshell, was used. The chief composition of eggshells is calcite. As it is a rich source of Ca, hence it is used with HCl to produce calcium chloride. Feldspar is an aluminosilicate mineral that bears potassium in the interstitial sites. To unlock the potassium from the interstitial sites, it was roasted with …

Custer v potash feldspar
Thanks for clearing that up re potash feldspar. The one I've recently bought was sold and labeled as Feldspar Potash, originally mined by Euroarce in Spain by the looks of the bag. The glaze cracks before firing. It can be smoothed over and fires okay but obviously would rather not spend ages smoothing over the cracks before firing.

Feldspar Distinctions, Characteristics, and Identification
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
In scientific terms, albite and microcline/orthoclase can form a solid solution. That is, an alkali feldspar can theoretically vary from sodium to potassium as its flux constituent. Soda feldspars actually tend to have at least 30% of their flux as potassium, while potash feldspars usually have at least 15% of their flux as sodium.

Of course, 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. Thus, in industry, potash feldspars are often used ...
