Phlogopite

Phlogopite is divided into dark phlogopite ( brown or green in various shades ) and light phlogopite ( pale yellow in various shades ). Light-colored phlogopite is transparent and has glass luster; dark-colored phlogopite is translucent. Glass luster to semi-metal luster, the cleavage surface is pearl luster. The sheet is elastic. Hardness 2─3. The proportion is 2.****2.*5. Not conductive. Colorless or brownish yellow under microscope transmission light. The main performance of phlogopite is slightly inferior to muscovite, but it has high heat resistance and is a good heat-resistant insulating material.
