Best Mohs Hardness Kits: Controlled Scratch Testing
Choose a hardness-testing system for repeatable property evidence—not as a one-test mineral naming device.
Choose equipment from the material and job first—not from the retailer first.
What is the best Mohs hardness kit?
A useful Mohs kit provides consistent reference points and a workflow that protects the specimen. Hardness is only one property and scratch testing is destructive, so it should be combined with other evidence and avoided on valuable surfaces when possible.
The test surface can be sacrificed.
Hardness is useful when you can expose/test a representative surface without damaging a specimen whose value depends on preservation.
One scratch result proves identity.
Weathering, coatings, aggregates and mixed minerals can mislead. Stack hardness with density, streak, luster, habit and context.
