The powdered form of a mineral is called a mineral powder. It is created by crushing and grinding a mineral into fine particles. Mineral powders are commonly used in various industries like cosmetics, pharmaceuticals, and manufacturing.
The mineral you are referring to is likely gypsum. Gypsum is a soft, colorless to light-colored mineral that can appear translucent and has good cleavage.
Mineral hardness measures a mineral's resistance to scratching, while streak is the color of the powdered form of a mineral. Hardness is determined by the Mohs scale, while streak is identified by rubbing the mineral across a porcelain plate to see the color left behind.
Color is the observable color of a mineral specimen in natural light. Streak is the color of a mineral when powdered. The color of a specific mineral specimen may be different than its streak color. Because many impurities can alter the color of a mineral, but not the streak, streak is a more accurate predictor in mineral identification.
The mineral that is sometimes confused with gold due to their similar color is pyrite, also known as fool's gold. Pyrite has a brassy, metallic yellow color that can easily be mistaken for gold by individuals who are not familiar with minerals. However, unlike gold, pyrite is a sulfide mineral that is not valuable or precious.
The mineral property identified by the color of the powder left behind when a mineral is rubbed across a surface is called the mineral's streak.
Obsidian. It commonly is dark because of the Fe contamination.
it is not a good idea to identify a rock or mineral by it's color because the color of the rock can change and when looking at facts on that rock/mineral it may not say the color that you have. that is why there are other ways as well as color. but don't get me wrong because some things can be identified by the color so it really depends.

Minerals can be identified by such as their color, streak, luster, and their hardness. What does streak, and luster mean?Streak-- Is the color of a mineral's powder for example: talc is a mineral and it is also powder and its streak is white.Luster-- Is the way a mineral reflects light from it's surface for example: glassy, pearly, silky, metallic and earthy can be words to describe luster.
The mineral you are referring to is likely gypsum. Gypsum is a soft, colorless to light-colored mineral that can appear translucent and has good cleavage.
