Feldspar is the name of a group of minerals. They are monoclinic, triclinic, orthorhombic, and hexagonal silicates. Feldspars are common, probably the most common mineral on Earth, being a constituent of the rock known as granite.
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.
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.
Orothoclase Feldspar belong to the silicates group.
The scientific name for feldspar is a group name that encompasses several different minerals. The most common type of feldspar found in Earth's crust is potassium feldspar, which has the scientific name KAlSi3O8.
No, talc is softer than feldspar on the Mohs scale of mineral hardness. Talc has a hardness of 1 while feldspar has a hardness of 6-6.5, which means that feldspar is resistant to being scratched by talc.

Plagioclase feldspar is a non-metallic mineral. It has 2 cleavages at nearly right angles. It is also differentiated from potassium feldspar because it contains striations. Potassium feldspar has 2 cleavages at nearly right angles.
Pretty much everywhere. About 60% of the earth's crust is feldspar.feldspar is found near volcanoes.because it it a type of igneous rockFeldspar if found mostly in Italy, Turkey and China
No, feldspar is not softer than pencil lead. Pencil lead, which is made of graphite, has a higher hardness on the Mohs scale compared to feldspar. Feldspar is typically around a 6 on the Mohs scale, while graphite is around 1-2.
Feldspars comprise a group of almost 20 related minerals and the ratio of elements differ from one type to another. The general ratio of atoms in common feldspar molecules isX:Al:Si:O = 1:(1 or 2):(3 or 2):8where X can be Na, K, or Ca.When X is Na or K, then Al = 1 and Si = 3and when X = Ca, then Al = 2 and Si = 2.
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 is a mineral found prety mutch anywhere.
Feldspar can be found in many things, including soap
