A streak test is used to determine a minerals streak color. This can help in the identification of minerals.
Different minerals produce different colour powders (know as the mineral's 'streak') when scratched. For instance, hematite has a red streak, calcite has a white streak and graphite has a black streak. There is also variation within some minerals, depending on impurities. It should be noted that some minerals are too hard to be scratched by porcelain, and will instead powder the porcelain, producing a misleading white streak.
False. No matter what happens to the mineral, the streak will always remain the same.
Galena's streak is gray, hematite's streak is deep maroon/brown.
The streak of a ruby is white.To find the streak of a ruby, or any gem stone, rub a piece of gem material on a tile and look at the color of the streak it leaves.
An emeralds streak is believed to be white, green, and/or yellow.
it can be white or gray but the word is STREAK
One physical property that can be used to distinguish hematite from other minerals is its streak color. Hematite typically leaves a reddish-brown streak when scratched against an unglazed porcelain plate. This can help differentiate it from other minerals that may have different streak colors.

The most useful physical property for identifying galena would be its metallic luster and its high density. Galena has a metallic luster and is one of the densest minerals, so these characteristics can be helpful in distinguishing it from other minerals.

Streak is the property of a mineral that is determined by rubbing the mineral on a special plate to reveal the color of its powdered form. This can help identify minerals because a mineral's streak color is often different from its external color.
Streak
Fluoride is an anion found in many compounds. It does not have a streak because streak is a property of minerals when they are scratched against a rough surface, leaving a colored trail.
I would say streak (Is that a physical property?). Gold has a yellow streak, pyrite a very distinguishable greenish-black to brownish-black. [A streak is obtained by scratching a mineral (or rock) on a streak plate (a white plate made of porcelain (floor tile-like), with a hardness of around 6.5 (Mohs scale)] If streak is not a physical property I would say hardness: gold has a hardness of 2.5, pyrite of around 6. I'm sure there are other usuable physical properties, as density for ex.
