After about the year 2000 the potassium content decreased by approx 2.5% in Custer feldspar. Reason I bring this up is because the article you linked to is from 2020 but the original recipe could well predate the newer low potassium content Custer feldspar. We don't know which potash feldspar Hopper was using when he wrote the original recipe.

Feldspar minerals are some of the most abundant minerals within the Earth's crust and are a common component of rocks. Species that are rich in potassium (K) are called potassium feldspars. Orthoclase, Microcline (Amazonite), and Sanidine are potassium feldspars. Feldspars rich in sodium (Na) or calcium (Ca) are plagioclase feldspars.

Labradorite, a plagioclase feldspar, has the chemical formula ((Ca, Na)(Al, Si)4O 8) while orthoclase, a potassium feldspar, has the chemical formula KAlSi 3 O 8. The minerals in the feldspar group are individual minerals that just happen to all be incredibly similar—so similar, that people lump them together.

POTASSIUM FELDSPAR (K-Feldspar) ("K-spar") Feldspar is a group of common silicate minerals. Feldspars are silicate minerals having one-fourth of all the silicons in SiO 2 replaced by aluminum (Si 4 O 8 to (Si 3 Al)O 8).When this happens, the (Si 3 Al)O 8 has a -1 electric charge. The charge is satisfied by the addition of one or more metals.

Feldspar - Mineralogy, Identification, Uses: Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, however, absolute; some …

Feldspars are aluminosilicates containing varying amounts of calcium, potassium, or sodium. In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase.

The parameters a and b for potassium feldspar have the values 0.4 and 1.2, respectively, whereas for sodium feldspar both have a value of 1.0. A mechanism for the dissolution reaction is proposed which is consistent with experimental observation. The analysis suggests that the dissolution is limited by the rate at which the hydrofluoric
