By rubbing a mineral on porcelain to obtain powder, you are observing its streak. The streak is the color of the powder produced when the mineral is scraped across a hard, unglazed surface, such as porcelain. This property helps in identifying the mineral, as the streak color can be different from the mineral's external color.
The color of a mineral in its powdered form is called streak. This can be determined by rubbing the mineral against a porcelain streak plate, which helps reveal the true color of the mineral's powder. The streak color can sometimes differ from the apparent color of the mineral, making it a useful property for identification.
The color left behind when a mineral is rubbed against a rough surface is called its streak. This property can help identify the mineral, as the streak color may differ from the mineral's external color. Streak is determined by rubbing the mineral on a porcelain plate or similar surface, and it is a useful characteristic in mineral identification.
An unglazed porcelain tile can be used to identify a mineral through a process known as a streak test. By rubbing the mineral across the surface of the tile, it leaves a streak of powder. The color of the streak can help identify the mineral based on its unique characteristics.
A mineral's streak is found by rubbing the mineral against a porcelain streak plate, which is unglazed and usually white. This process leaves a powdered form of the mineral on the plate, revealing the true color of the mineral in its powdered state. The streak can be useful for identification, as it often differs from the mineral's external color.
Rubbing a rock against porcelain can test the hardness of the rock. If the rock leaves a scratch on the porcelain, it indicates that the rock has a higher hardness level than the porcelain. This can help in identifying the relative hardness of the rock based on the Mohs scale.
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.

The color of a mineral in powdered form is called its streak color. It is determined by rubbing the mineral against an unglazed porcelain plate to produce a streak.
By rubbing mineral against a piece of porcelain tile, the objective of the test is to observe the hardness of the mineral.

An unglazed porcelain tile can be used to identify a mineral through a process known as a streak test. By rubbing the mineral across the surface of the tile, it leaves a streak of powder. The color of the streak can help identify the mineral based on its unique characteristics.
You could test for the property of hardness by seeing which mineral scratches the other. The mineral that scratches the other is the harder one.
streak
The test is called a streak test and it leaves a powdered form of the mineral on the porcelain. The powdered mineral reveals the true color, of the mineral specimen, which may or may not match the color of the specimen.
The streak of a mineral refers to the color left on a streak plate after rubbing a mineral across its surface. A streak plate can be as simple as the unglazed side of a porcelain tile. The streak is the mineral in a powdered form from abrasion with the hard, slightly textured surface of the unglazed porcelain streak plate. The streak color may differ from the color observed in a specimen. Coloration of mineral specimens is sometimes due to impurities. In a powdered form, the impurities are not abundant enough to cause coloration in the streak, thus revealing the true color of the mineral. The streak is used as an aid in the identification of a mineral.a streak mark on a flat surface
