Moh’s Hardness Testing Pencils Set of hardness testing pencils: 3-9. Mineral embedded in a brass holder with wooden handle. Supplied in a boxed set with notes.

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. The test is useful because most specimens of a given mineral are very close to the same hardness. This makes hardness a reliable diagnostic property for most minerals.
