The system you're referring to is likely the Mohs scale of mineral hardness. Developed by the German geologist Friedrich Mohs in 1812, this scale ranks minerals based on their scratch resistance, with hardness values ranging from 1 to 10.
1. **Talc** - Softest (1)
2. **Gypsum** - (2)
3. **Calcite** - (3)
4. **Fluorite** - (4)
5. **Apatite** - (5)
6. **Orthoclase Feldspar** - (6)
7. **Quartz** - (7)
8. **Topaz** - (8)
9. **Corundum** - (9)
10. **Diamond** - Hardest (10)
A material can scratch another if it has a higher number on the Mohs scale. For example, a mineral rated 7 (Quartz) can scratch anything rated lower than 7, but it cannot scratch anything rated higher than 7 (e.g., Topaz). This scale is widely used in geology and mineralogy for identifying minerals and assessing their properties.
