Question

Streak may be a more reliable property than color to help you identify a mineral. Streak is the color of a mineral when it’s powdered. Even a mineral that comes in different colors will have the same color streak. That means that a mineral’s streak might be different from its main color. Calcite, for example, may be white, yellow, brown, orange, pink or many other colors. It can also be multicolored. But calcite always has a white streak. Streak can help distinguish minerals that have the same or similar main color. You can test a mineral’s streak by rubbing it against a streak plate or a white tile.
