Review on π¬ Measuring Mohs Hardness Kit Specimens by Guillo Tilden
Somewhat useful
The bricks # 6 and #9 were marked with the same symbol. No point below #9 as shown in the description. Someday I'll find out what's what. Stone #4 was 1/4" by 1/8", barely big enough to take the label (definitely not the 1" in the description). As noted, the description does not mention that stone # 1 contains asbestos In my case, stone #1 was in a small torn plastic bag.
Pros
- Great for me
Cons
- No instructions
