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). Of course, real potash feldspars also have small amounts of CaO, MgO, Fe 2 O 3, etc.

In This Section. Published Sep 27, 2023. Feldspars are important ingredients in clay bodies and glazes. In both applications, their primary function is to supply fluxes to the formulations, but they also provide additional alumina (Al2O3) and silica …

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.

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.

A pilot-scale study for potash recovery from feldspar using a mixture of CaCl 2 and CaCO 3 was reported by Zhang et al. . There is no specific issue during the pilot-scale study of extraction, however, a sharp increase in potash recovery was observed above the melting point (700–800 °C) of roasting additive. ...

In this paper, the molecular sieves with high added value were creatively prepared from roasting clinker obtained by the process that NaOH-Na2CO3 mixed alkali as auxiliary agent calcined potash feldspar, which could extract the silicon it contains. Firstly, the optimum roasting conditions for SiO2 extraction rate were determined through single …
