Decoding the 9H Rating
The “9H” rating is derived from the Mohs hardness scale, which measures the scratch resistance of various minerals and materials. The scale consists of ten minerals, ranked from 1 (the softest, talc) to 10 (the hardest, diamond).
Understanding the Mohs Hardness Scale
- 1 (Talc): Soft and easily scratched.
- 2 (Gypsum): Slightly harder but still very soft.
- 3 (Calcite): Has more scratch resistance but not much.
- 4 (Fluorite): Moderate hardness, can be scratched by harder materials.
- 5 (Apatite): Good hardness, more resistant to scratches.
- 6 (Orthoclase Feldspar): Fairly hard, can withstand more abrasion.
- 7 (Quartz): Known for its durability and scratch resistance.
- 8 (Topaz): Harder stone, can scratch many calculations.
- 9 (Corundum): Comprises sapphires and rubies, highly scratch-resistant.
- 10 (Diamond): The hardest natural material known.
The “H” in 9H indicates that the tempered glass is resistant to scratches from materials ranked up to the 9th level on the scale, which means it can resist scratches from almost all everyday objects.
