The color of the powder left on the rough surface by a mineral is called its streak. The streak plate is a hard surface that helps to determine the different shades and characteristics of the minerals that is rubbed on it.
Why is a streak a more reliable property than the actual color of the mineral?
A streak is considered a more reliable property than the actual color of a mineral because it reflects the mineral's true color in powdered form, which is less affected by impurities or surface alterations.

In contrast, the streak remains consistent for a given mineral, providing a more accurate and dependable characteristic for identification.
