How can an unglazed porcelain tile be used to identify a mineral?
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.
Why can't the streak test be used to identify all minerals?
Because some minerals dont have a streak, or may share a streak colour with another mineral.
Why are some minerals easier to identify than others?
Minerals vary in ways they can be distinduished. Some are easy to identify by hardness, color , streak, or luster
What isn't a streak test used to help identify every mineral?
Because some minerals have the same color streak, don't have a streak, or the streak is hard to see
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.
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.

What are two tests scientists use to identify minerals?
hardness and streak

How do you identify minerals I Me My We Our?
Minerals have certain properties, or characteristics, that help to identify them. Minerals can be identified by their color, luster, streak, cleavage, hardness, specific gravity, and even by their chemical composition.
What isn't a streak test used to help identify every mineral?
Because some minerals have the same color streak, don't have a streak, or the streak is hard to see
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.
What does streak mean in science term?
In mineralogy, streak is the powder from a mineral when you rub it against a light colored hard surface. Streak is used to identify some minerals.
Why isn't streak used to identify every mineral?
cause some minerals have the same color streak as others
