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.
