identifying the mineral
A streak plate is used to determine the streak colour of a mineral. You take the mineral and scratch it against the streak plate, and it will create a coloured streak on the plate. The streak is not always the same colour as the mineral itself.
The rock used to find a mineral's streak color is unglazed porcelain.
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. The streak is used as an aid in the identification of minerals.
Shale is a type of rock, not a mineral. Streak is used to help classify minerals. It can leave a streak, but it doesn't mean anything.
A white tile plate is used. Some minerals leave a streak; others don't.
No one knows.
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.
It's called a streak plate.
A streak is a line or band of a different color or texture from its surroundings, often used to describe patterns seen in minerals or rocks. It can be used in mineral identification to help differentiate one mineral from another based on its unique streak color.
The mineral Quartz leaves a colorless streak.
The streak of the mineral is the mineral's powder color
The lack of a streak would indicate that the mineral is harder than the streak plate, or the color of the streak is the same as the color of the streak plate.
