Moh's Scale of Hardness Kit

The Moh scale is not a regular, linear progression. Some of the minerals are quite close to each other in hardness, while others are farther apart. However, Moh's Hardness is an extremely useful measure when trying to identify a mineral.

If your unknown mineral can scratch fluorite but not apatite, for example, then you know it has a hardness of 4.0 or 4.5.  If fluorite cannot scratch the mineral at all, you would narrow this to 4.5.  

To see if a successful scratch was made, first clean away any dust or powder that might have formed. It often helps to examine the specimen with a hand lens or a magnifying glass.

This mineral hardness collection has nine specimens, from talc (hardness 1) through corundum (hardness 9).
