- ❤Mohs hardness: A standard indicating the hardness of minerals. The scratching method is used to scratch the surface of the tested mineral with a conical diamond needle to produce scratches. It is customary to use Mohs hardness in mineralogy or gemology.
- ❤Test grade: Gypsum 2, Calcite 3, Fluorite 4, Apatite 5, Orthoclase 6, Quartz 7, Topaz 8, Corundum 9.
- ❤Easy to carry: Mohs hardness is easy to apply and is often used in field operations. These hardness values are judged by rubbing against each other, and are relative relationships, not linear proportions (it cannot be said that hardness 6 is 3 times harder than hardness 2).
- ❤Hardness test kit: It is a multi-faceted shape that has been carefully processed, making it more convenient and durable to use.
- ❤Wide application: suitable for gems, jade, ceramic tiles, floors, glass, mobile phone screens, minerals, concrete, etc.
