How many levels of ceramic tile hardness can be judged by Mohs hardness, that is, the glaze of ceramic tile is graded by standard modulus, and which level of modulus is used to draw the glaze, then it is lower than that level. Mohs hardness is divided into the following ten grades: 1 talc, 2 gypsum, 3 calcite, 4 fluorite, 5 apatite, 6 orthoclase, 7 aging, 8 Shi Ying, 9 corundum and 10 diamond.

If you don't need to know the exact value, you just need to make a rough judgment, and you can also check the hardness by knocking bricks. If the sound of knocking bricks is crisp, a little metallic sound indicates that the hardness is high; If the voice is hoarse, it means that the hardness of the brick is low, or there may be cracks hidden in the brick.

The hardness of tiles is not as hard as possible, everything has a degree. The hardness of ceramic tiles is good at grade four or five. For example, the hardness of domestic first-line brands of Asian tiles is at grade five, and most tiles are at grade four.
