Why is streak more reliable than color when identifying a mineral?
The streak is the mineral in a powdered form from abrasion with the hard, slightly textured surface of an unglazed porcelain streak plate. The streak color may differ from the color observed in a specimen. Coloration of mineral specimens is sometimes due to impurities. In a powdered form, the impurities are not abundant enough to cause coloration in the streak, thus revealing the true color of the mineral. == ==
