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. The streak is used as an aid in the identification of minerals.
A streak plate, typically made of unglazed porcelain, is used to find the streak of a mineral by rubbing the mineral across the plate to leave a colored powdery streak. This streak color can help identify the mineral because it is often distinct from the color of the mineral itself.
If you know what mineral it is you could look it up. If you don't have a streak plate available, you could crush some of the mineral with a hammer into a fine powder. What you'll be left with is the streak color.
To obtain a minerals streak you would get a piece of the mineral and rub it against something that is strong enough to erode a little of it.
