β 14y agoPyrite is a mineral that has a streak that is greenish black, even though its external color is brassy yellow. This difference in color is due to the oxidation of iron in pyrite.
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.
No, streak color can vary depending on the mineral. Streak color is the color of the powdered form of a mineral, which may be different from the color of the mineral itself.
Luster refers to how a mineral's surface reflects light - it can be metallic, glassy, pearly, or dull. Streak is the color of a mineral's powder when rubbed against an unglazed tile and can help identify the mineral even if its external color is different.
The streak of a mineral can distinguish between two samples that have the same color. The streak is often a different color. To test streak, use a streak plate. This is a piece of unglazed porcelain, like the back side of a tile.
The color of powder scraped off a mineral when rubbed against a hard rough surface is known as the mineral's streak. This property helps in identifying minerals as it can sometimes differ from the mineral's external color.

The color of a mineral in powdered form is called the mineral's Streak

Because many impurities can alter the color of a mineral, but not the streak, streak is a more accurate predictor in mineral identification.
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.
No, streak refers to the color of a mineral when it is crushed and powdered. It helps in identifying minerals as the streak color can be different from the color of the mineral.

The property of a mineral that shows the color of its powder is called streak. Streak is determined by rubbing the mineral against an unglazed porcelain plate to produce a colored powder. This color can sometimes be different from the color of the mineral itself.
By scraping the mineral against a piece of tile. The color of the mineral is actually sometimes completely different than the streak.
