Moh's Scale of Hardness Kit. This mineral hardness collection has nine specimens, from talc (hardness 1) through corundum (hardness 9).
#C2357.....$15.99
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 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.
