Monoclinic system. The crystals are usually thin mica flakes. The color is brown, yellow brown and golden yellow. Streaks are white or brown. Luster pearl, metal or glass, slightly transparent to transparent. Cleavage according to the bottom, very complete. The hardness is 1-1.5. The specific gravity is 2.4-2.7.

Produced in Henan, Shandong, Shanxi, Sichuan and other places.

[chemical composition] it contains magnesium oxide 14-23%, iron oxide 5-17%, ferrous oxide 1-3%, silicon oxide 37-42%, lead oxide 10-13%, water 8-18% and other impurities. The products sold in Beijing also contain a large amount of iron ions, medium amounts of ferrous ions, lead ions, silicate ions, small amounts of magnesium ions, manganese ions and trace amounts of potassium ions.

[processing] jinjingshi: wash the soil and grind it. Calcined Jinjing stone: take pure Jinjing stone pieces, calcine them with pine wood for about one day, and take them out after cooling. Or use pure gold and fine stone pieces, mix well with chlorite and sodium nitrate, burn them with charcoal fire to make them into a ball, and calcine them until the sodium nitrate is exhausted. The color is as golden as gold plating. Take them out.
