It's called a streak plate.
What else can I help you with?
When some minerals are rubbed across unglazed porcelain they leave a streak of powdered material true or false?
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.
What is a piece of unglazed porcelain to test a mineral's streak called?
A streak plate
How do you test a minerals streak?
By rubbing a mineral against a piece of unglazed porcelain tile From Prentice Hall textbook: Inside Earth
The color of the powder that a mineral leaves on a piece of white unglazed porcelain is called?
The color of the powder that a mineral leaves on a piece of white unglazed porcelain is called the "streak." This is a helpful characteristic used in mineral identification.
What mineral produces a black streak when rubbed on a piece of unglazed porcelain?
The mineral that produces a black streak when rubbed on unglazed porcelain is hematite. Hematite is an iron oxide mineral that typically appears metallic gray or reddish-brown in color, but its streak, which is the color of the powder it leaves behind, is characteristically black. This property is often used to help identify minerals in hand specimens.
When you drag a piece of calcite across an unglazed porcelain plate itleaves behind a white line. what mineral characteristic does this relate to?
The white line left behind when dragging calcite across an unglazed porcelain plate relates to the mineral's hardness and its ability to leave a streak. This characteristic is often used in mineral identification, where the streak color can help distinguish between different minerals. Calcite has a hardness of 3 on the Mohs scale, allowing it to produce a visible streak on the porcelain surface.
What does a mineral and streak tell you and how do you test for it?
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.

What is a streak when it comes to talking about science?
'streak' is the color that a mineral will leave when rubbed on a piece of unglazed porcelain. It is used to help identify the mineral. For example, arsenopyrite looks very similar to gold, but has a dark grey or black streak. Gold has a yellow streak.
What is used to find the streak of a mineral?
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.
