Which mineral leaves a green-black powder when rubbed against an unglazed porcelain plate?
there is no name for the color, but there is the "streak" of a mineral, meaning the color of its streak.
Talc has a streak color of white. This means that when scraped across a white, unglazed porcelain plate, talc leaves behind a white streak.
To find the streak of a rock, you can rub the rock against an unglazed white porcelain tile to observe the color of the powder left behind. The color of the streak can help identify the minerals present in the rock.
true
You identify minerals through a streak test. This involves taking the tile and the mineral to be identified and rubbing them together. This produces a colored streak on the tile, which can be used to identify the mineral. Consult a field guide for specific colors.
True. This test is known as the streak test and is often used to help identify minerals based on the color of the streak they leave behind on a piece of unglazed porcelain.

The white line left behind when dragging calcite across unglazed porcelain is due to the abrasion of the softer calcite mineral against the harder porcelain surface. The powdery residue created is caused by the calcite being scratched off and deposited on the porcelain as a result of the friction between the two materials.

true
A streak test is used to determine a minerals streak color. This can help in with the identification of minerals. A streak test is performed by rubbing the mineral on an unglazed ceraminc tile, then observing the color of the streak which is left behind. All minerals do not leave streaks. Harder minerals will not streak, but this can also be used as a tool for identifying the mineral, if you are familiar with the hardness scale.

The streak test is used to identify minerals by rubbing the mineral against an unglazed porcelain plate to observe the color of the powder left behind. This color can sometimes be different from the outward color of the mineral and is helpful in distinguishing between similar-looking minerals.
Shale normally leaves a brown streak on unglazed porcelain plates. However, shale can also leave a white streak on unglazed porcelain plates.
The property being measured is the mineral's streak color. The streak test involves scraping the mineral on an unglazed porcelain tile to see the color of the powdered residue left behind.
