3.1: Front Matter

Your mineral kits will likely contain several items of a known hardness. The glass plate and steel nail have a hardness of 5.5, a copper penny, plate or sheet has a hardness of 3, and your fingernail has a hardness of 2.5. A mineral scratched by your fingernail is relatively soft, and its assessed hardness would be <2.5.

Physical Characteristics of Rocks

Geologist define rock as aggregates or mass composed of one or more commonly, several of minerals. There are few exceptions to this rule: not all rocks are composed of minerals-for example, coal. Engineers (or contractor) define rock to be hard, durable material that can't be excavated without blasting. The definition is based on strength and durability.

Mohs hardness | Definition, Table, Examples, & Facts

Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.

The Hardest Rock and Hardest Mineral on Earth

When measuring the hardness of rocks, many like to use the Mohs scale of harness used for minerals. Basically the Mohs scale of hardness measures the ability of one mineral to visibly scratch another mineral. It is said that using the Mohs scale of hardness on rocks can be misleading as rocks will vary with their mineral contents.
