Orthoclase. Orthoclase is frequently known as potassium feldspar or K-spar, and is easily distinguished from the plagioclase feldspars in hand sample by its lack of striations. In thin section, alkali feldspar grains often look like they're sprinkled with dirt (PPL) or tiny confetti (XPL). You can find the explanation on the alkali feldspar page.

This feldspar is distinguished from the orthoclase form by its content of calcium and sodium. The feldspars are the most abundant minerals on the earth. In the Bowen reaction series, plagioclase can be seen to form throughout the process of magma crystallization in what is called the continuous reaction series. As the cooling continues, the ...

The moonstone effect, which is called ADUIARESCENE (ad-u-lar-ESS-ence), is caused by a concentration of the soda-type feldspar (albite) in oriented positions within the main mass of orthoclase. Some moonstones contain enough albite to have properties nearer those of albite than of orthoclase; on the whole, however, moonstone is regarded as a ...

Orthoclase, or orthoclase feldspar (endmember formula KAlSi3O8), is an important tectosilicate mineral which forms igneous rock. The name is from the Ancient Greek for "straight fracture," because its two cleavage planes are at right angles to each other. It is a type of potassium feldspar, also known as K-feldspar.

On the list are quartz and orthoclase. (Orthoclase is one of the most abundant types of feldspar.) By looking at the scale, it is clear that quartz with a hardness of 7 is harder than the orthoclase feldspar with a hardness of 6. Since there are multiple types of feldspar, the hardness does vary, but the range is small, between 6 and 6.5.
