How to Identify Minerals in 10 Steps (Photos)

To do a streak test, you scrape the mineral across an unglazed porcelain plate. The plate is harder than many minerals, causing the minerals to leave a streak of powder on the plate. The color of the streak often differs from the color of the larger mineral sample. If you did a streak test on the yellowgold pyrite, you would see a blackish streak.

How Do Geologists Identify Minerals?

A streak test is accomplished by rubbing the mineral on a porcelain plate, also known as a streak plate. The color of the streak left by the mineral is sometimes different from the color of the mineral itself. A streak test comes in handy when identifying minerals such as hematite.

Mohs Hardness Scale: Testing the Resistance to Being Scratched

What is Mohs Hardness Scale? One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left). The test is useful because most specimens of a given mineral are very close to the same hardness.
