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. == ==
What is the difference between color and streak in minerals?
Color is the observable color of a mineral specimen in natural light. Streak is the color of a mineral when powdered. The color of a specific mineral specimen may be different than its streak color. Because many impurities can alter the color of a mineral, but not the streak, streak is a more accurate predictor in mineral identification.
