The streak of a mineral refers to the color left on a streak plate after rubbing a mineral across its surface. A streak plate can be as simple as the unglazed side of a porcelain tile. The streak is the mineral in a powdered form from abrasion with the hard, slightly textured surface of the 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. The streak is used as an aid in the identification of a mineral.a streak mark on a flat surface

You identify minerals through a streak test. This involves taking the tile and the mineral to be identified and rubbing them together. This produces a colored streak on the tile, which can be used to identify the mineral. Consult a field guide for specific colors.

Streak is a method used to help identify minerals. A mineral can have very similar characteristics such as luster, colour, hardness, specific gravity ect, but even minerals with very similar characteristics including colour can have different streaks...which is the 'colour' the mineral makes on a scratch plate when drawn accross it in a stroke..thus creating the streak.
