5 Pack Mohs Hardness Test Kit, 5-9 Scratch Tester Industrial, Mineral Identification, for Testing Mineral Jewellery Jade Glass Ceramic Tile Concrete

Product specifications: Test steps: 1. First make an indirect visual assessment of the hardness of the sample. 2. Find an inconspicuous place and scratch the sample with a hardness pen that is 1 to 2 levels lower than the visual hardness. If it cannot be scratched, it means that the hardness of the sample is higher than the hardness of the hardness pen. Then use a higher hardness pen. carve. 3. Pay attention to the moderate carving intensity, neither too light nor too heavy. 4. If there is powder during the marking test, it is necessary to judge whether it is the powder of the sample or the loss powder of the test pen, and do not make a misjudgment.
