Is streak the color of powder?

Streak refers to the color of a mineral in powder form.


What is the definition of mineral streak?

Mineral streak is the color of the powder produced when a mineral is scratched on a porcelain streak plate. It is a useful property for identifying minerals, as different minerals can leave distinctively colored streaks.


Why Is Streak A Useful Property For Identifying Minerals?

The streak of a mineral is much more accurate in identifying a mineral than color. The streak of a mineral can distinguish minerals with metallic and non-metallic luster. For example, metallic minerals generally have a dark streak whereas non-metallic luster minerals often have a light colored streak.


What is the color of the powder that a mineral leaves went is scratched across a special plate?

The color of the powder left by a mineral when scratched across a special plate is called the streak color. This color may differ from the actual color of the mineral itself and is a helpful characteristic in mineral identification.


If a mineral has no streak is it metallic?

When identifying minerals, having no streak is a property of hardness. A streak plate has a hardness of ~7(Moh's Scale). Thus any mineral having a hardness greater than 7 will have no streak.Metallic is the description of luster. Or the general appearance of a mineral surface in reflected light.If you were refering to the mineral having metal elements in it, streak is actually very useful for identifying them. Many minerals that are composed of non-metals have a white streak which can appear to be no streak, however there are also many minerals with no streak which are composed of non-metallic minerals (Diamond).
