Firstly, the optimum roasting conditions for SiO2 extraction rate were determined through single …
Soda will generally flux more than potash. Therefore, you will get different effects. Also, sodium is more "reactive" with other chemistry than potassium. For the sake of your kiln shelves, don't assume you can just substitute one for one. Your soda will drive a lower maturing temp compared to potash. Personally, I feel that predictable and ...

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.

Feldspars are hard minerals, all of them with a hardness of 6 on the Mohs scale. This lies between the hardness of a steel knife (5.5) and the hardness of quartz (7). In fact, feldspar is the standard for hardness 6 in the Mohs scale. Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff.

It is a ceramic grade, high potash feldspar and is available in crude, 200, 325 mesh and chip form.
Changing the feldspar from potash to soda won't necessarily bring it all the way from cone 10 down to cone 6, but it will definitely bring it down. How far depends on the rest of glaze formula. But it is a good first step to lowering the melt. Potash spars can be used at cone 6, but they do melt differently than soda spars, and give a different ...

Thus, at the feldspar surface, silicon is removed as a volatile fluoride, while the other constituent elements are left exposed in a thin gelatinous surface film of aluminum fluorosilicate. In this way, the residual potassium from the potash feldspars reacts with the sodium cobaltinitrite to form the yellow potassium cobaltinitrite stain.
