recognize and identify an observational fact with a mineral property for example, "the testing of a mineral against a glass plate is a test of relative hardness on the Mohs scale" make inferences based on test results for example, "because the sample creates a scratch in a glass plate, it's relative Mohs hardness must be greater than about 5.5"

The streak test is an easy way to determine the color of a mineral in powdered form. It is done by scraping a specimen of that mineral across an unglazed piece of porcelain known as a streak plate.

Streak is the color of the powdered mineral, which is usually more useful for identification than the color of the whole mineral sample. Rubbing the mineral on a streak plate will produce a streak. A streak plate can be made from the unglazed back side of a white porcelain bathroom or kitchen tile.

Aug 18, 2016· A streak plate is used to determine the color of the streak or powder of a mineral. The color of the streak or powder is extremely helpful in identifying some minerals. For example, hematite is a mineral that may be any one of several different colors, but its streak or powder is always reddish brown.

Streak is more often distinctive for metallic minerals, in contrast to nonmetallic minerals whose body colour is created by allochromatic elements. Streak testing is constrained by the hardness of the mineral, as those harder than 7 powder the streak plate

On the Mohs scale, a streak plate (unglazed porcelain) has a hardness of approximately 7.0. Using these ordinary materials of known hardness can be a simple way to approximate the position of a mineral on the scale. Intermediate hardness. The table below

Streak is the color of a minerals powder. Streak is a more reliable property than color because streak does not vary. Minerals that are the same color may have a different colored streak. Many minerals, such as the quartz in the Figure 3, do not have streak. To check streak, scrape the mineral across an unglazed porcelain plate (Figure 5).

Mineral Mineral Hardness Hardness (H) is the resistance of a mineral to scratching. It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel tool.
