Feldspar is a mineral found prety mutch anywhere.
The most common element found in orthoclase feldspar but not in plagioclase feldspar is potassium (K). Orthoclase is a potassium-rich feldspar, typically represented by the chemical formula KAlSi3O8. In contrast, plagioclase feldspar is a solid-solution series that primarily consists of sodium (Na) and calcium (Ca) in its composition, lacking potassium.
Feldspar is a 6 on the hardness level and diamond is the hardest t 10. Feldspar is not very heavy- about the weight of granite or quartz (the average rock)
Feldspar can be a variety of colors: clear, gray, white, tan, pink, brown, or red.

Feldspar's fracture is brittle
The fracture of feldspar is conchoidal or brittle.
The fracture of feldspar is conchoidal or brittle.
Fluorite is harder than feldspar, so scratching fluorite against feldspar would cause the fluorite to scratch the feldspar. This means the fluorite would leave a mark on the feldspar, showing that fluorite is harder than feldspar.
Feldspar can be found in many things, including soap
Feldspar
Feldspar is found in North Carolina primarily in the Spruce Pine Mining District, which is located in the western part of the state. This area is known for producing high-quality feldspar, including both potassium feldspar and plagioclase feldspar. The feldspar from this region is used in various industries such as ceramics, glassmaking, and abrasives.
Feldspar minerals comes in a variety of colors and chemical formulas. The most common pink feldspar is orthoclase.
A steel nail can scratch feldspar but not quartz. Feldspar has a hardness of 6 on the Mohs scale, while quartz has a hardness of 7.
Feldspar, the mineral, is not magnetic. Most, but not all, magnetic minerals contain iron.
The luster of feldspar is considered vitreous.
Granite contains plagioclase feldspar and potassium feldspar. It really depends on the composition of the magma from which it forms. If the granite has a lot of pink in it, chances are it is potassium feldspar (K-Spar). If it is dominated by white, then the feldspar is probably plag.
