Introduce students to the timeless principles of mineral hardness with the traditional Scale of Hardness Collection! This indispensable set features nine key minerals in Mohs Scale of Hardness, meticulously chosen to represent a range of hardness levels from talc, the softest mineral at #1, to corundum, the ninth hardest at #9. Excluded from this set is diamond, the hardest mineral, at #10.

 

Each specimen measures approximately 1" x 1.5" and is number-coded for easy identification and classification. Students can explore the tactile differences and scratch resistance of each mineral, gaining firsthand experience in assessing hardness according to the Mohs Scale.

 

Empower students to conduct experiments, perform tests, and deepen their understanding of mineral properties with the Mohs Scale collection. Whether used as a standalone resource or integrated into larger geological studies, this set provides a foundational understanding of mineral hardness that is both engaging and educational.
