The color of a mineral's streak depends on the color of the mineral?

Yes all minerals have streaks, but since minerals have different levels of hardness it's harder to make some streaks than others that are easier to make like the streak of graphite.

What is the difference between a minerals color and streak?
Color is what you observe when you look at a mineral. Streak is the color of the mineral when in a fine powder form. This can be observed by drawing a sample of the mineral over an unglazed porcelain tile and noting the color of the line left on the tile.
What is the difference between color and streak in minerals?
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.
What is the first step to measure the streak of a mineral?
To measure the streak color of a mineral, the first step is to obtain a sample of the mineral you want to test. Step 2, find a nice, clean ceramic tile with a white unglazed back. Step 3, using a corner of your mineral, move it across the back of the tile while pushing down enough to see the streak and its color. Step 4, compare the streak color with samples of known minerals, from color photos in a book of minerals, or from a written description of minerals and their streak colors.
Why is streak more reliable than color when identifying a mineral?
The streak is the mineral in a powdered form from abrasion with the hard, slightly textured surface of an 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. == ==
Why isn't streak used to identify every mineral?
cause some minerals have the same color streak as others
What is the color of a mineral in powder form?
It's called the minerals streak
What is the color of a minerals powder called?
there is no name for the color, but there is the "streak" of a mineral, meaning the color of its streak.
How do you determine minerals streak?
The color of a mineral in powdered form is called the mineral's Streak
The color of a minerals powder is its what?
The color of a mineral in powdered form is called the streak color.
Which mineral rock is used to find the streak color of minerals?
The rock used to find a mineral's streak color is unglazed porcelain.

How do you identify minerals according to streak?
Minerals can be identified by their streak, which is the color of the mineral when it is broken down into a powder. To test a mineral's streak, a streak plate (usually made of unglazed porcelain) is used. The streak is usually compared to a streak color chart, which contains the colors of a variety of minerals. To test a mineral for its streak, take a small piece of the mineral and rub it on the streak plate. The resulting powder is then compared to the streak chart to identify the mineral. Streak is an important property of minerals because it is more reliable than the external color of the mineral. External color can be altered by impurities and oxidation, but the streak of a mineral does not change. Therefore, testing a mineral's streak is an effective way of identifying it.When identifying minerals according to streak, it is important to consider the following properties: Color - the color of the powder when rubbed on the streak plate. Luster - the shine of the powder when rubbed on the streak plate. Texture - the feel of the powder when rubbed on the streak plate. Opacity - the transparency of the powder when rubbed on the streak plate.By considering these properties when testing a mineral's streak, it is possible to identify the mineral accurately and quickly.
Color of powered mineral?
It's referred to as the streak, the color of which is used as an identifying characteristic of minerals.
What is the Color of a mineral when crushed to a powder?
Different minerals have different colors, actually.
What test is used to identify a minerals color?
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.
Why is streak an important physical property of minerals?
A streak test is used to determine a minerals streak color. This can help in the identification of minerals.
