Deluxe Hardness Picks by Mineralab

Deluxe Hardness Pick Set for Mineral Identification



Hardness picks make hardness testing a more precise process - especially when testing small specimens or mineral grains within a rock. The point of the pick can easily be placed on the part of the specimen that you want to test. The scratches that you make or trails of metal that are left behind are usually very easy to distinguish.

Simply hold the pick in your hand like a pencil and place it on the area that you would like to test. Then, with pressure, drag the point across the surface of the specimen. It will either leave a scratch, slide without scratching, or leave a trail of metal behind.

The set includes eight points - for Mohs hardness of 2, 3, 4, 5, 6, 7, 8 and 9. The 2 is a plastic point, the 3 is a copper point, the others are alloys carefully selected to match the hardness of the Mohs index minerals.

The set includes:
  • Four double ended picks with hardness points of 2-9 on Mohs hardness scale
  • A grinding plate for sharpening your points
  • Streak plate
  • Glass plate for quick "hard" or "soft" determination
  • A hardness plate with a hardness of 3.5
  • Magnet
  • Hardness tables of 250 minerals (alphabetical and in order of hardness)
  • Hardness testing instructions
  • All of this in a compact (7" x 2 1/2" x 1 5/8") wooden carry case
