Free Printable Mohs Scale of Hardness Chart

Download and print the Mohs Scale of Mineral Hardness - a classic reference for identifying minerals by their scratch resistance. Ideal for geology classrooms, rock collectors, and earth science enthusiasts.

The Mohs scale ranks minerals from 1 (softest, talc) to 10 (hardest, diamond). This printable chart helps students and collectors compare mineral samples quickly and accurately.

No sign-up required - just download and print. Includes labelled and blank charts for learning and testing mineral hardness identification.

Quick Facts About the Mohs Scale

• The scale was created in 1812 by German mineralogist Friedrich Mohs.
• It compares how easily one mineral can scratch another.
• Diamond is the hardest known natural mineral (10 on the scale).
• Talc is the softest mineral, easily scratched by a fingernail.
• The Mohs scale is relative, not linear - each step is not an equal increase in hardness.
