What Is Feldspar?

Feldspar is a general name for a group of rock-forming minerals. They make up about 60% of the Earth’s crust. Feldspars are aluminosilicate minerals containing sodium, potassium, calcium, or barium. These minerals are important in geology and industry.

Feldspar is divided into two main classes:

• Potassium Feldspar (K-feldspar): Includes orthoclase, sanidine, and microcline. They are rich in potassium.
• Plagioclase Feldspar: Includes albite, oligoclase, and labradorite. They are mixtures of sodium and calcium.

Feldspar comes in different colors. They can be white, pink, gray, or brown. The color depends on impurities. They also have a glassy or pearly luster.

Feldspar is relatively hard. Their Mohs hardness is 6-6.5. They are resistant to weathering. This makes them useful in many applications. Understanding the different types is helpful. It helps in choosing the right feldspar for specific uses. It can ensure the best results.

What Are The Uses Of Feldspar?
