Mohs Hardness Test Kit, 1-10 Scratch Tester with Storage Box, Inlaid with Natural Minerals, Relative Wear Resistance Testing, for Ceramic Tile, Floor, Glass

Description: - The Mohs Hardness Pen set consists of 10 pens made from a unique inlay of natural minerals. - Each pen utilizes the edges and corners of these minerals to accurately scratch the sample being tested, allowing for precise judgment of its hardness. - If a scratch appears, it indicates that the sample's hardness is lower than that of the hardness pen. Conversely, if no scratch is present, it means the sample's hardness exceeds that of the pen. Specifications: Name: Mohs Hardness Test Kit Pen holder material: Stainless steel Measuring range: 1-10 levels Pen size: 116 mm x 7 mm Package size: 200 mm x 160 mm x 50 mm Hardness standard: 1# Talc, 2# Gypsum, 3# Calcite, 4# Fluorite, 5# Apatite, 6# Orthoclase, 7# Quartz, 8# Topaz, 9# Corundum, 10# Diamond Packing list: 10* Hardness Pens 1* Storage Box

• [Mohs Hardness Pen]: The Mohs hardness pen is based on the hardness of 10 different minerals, and materials of different hardness are selected to simulate alternative minerals to create a mineral-like scratch pen, which is used to detect the Mohs hardness of various surfaces
• [10 Test Grade]: Talc-1, Gypsum-2, Calcite-3, Fluorite-4, Apatite-5, Orthoclase-6, Quartz-7, Topaz-8, Corundum-9, Diamond-10
• [Stainless Steel Material]: The value is accurate. There are 10 hardness pens in the box, each one is 130mm long and 6mm in diameter. Made of pure stainless steel, with good texture and exquisite appearance
• [Note]: Note that the intensity of the engraving should be moderate, neither too light nor too heavy, because the direct engraving method to determine the hardness is damaging to gemstones. This method is generally not allowed to be used on finished gemstones
• [Application]: Commonly used for Mohs hardness determination on the surfaces of various types of solidified floors, floor tiles, ceramic tiles, concrete floor construction industry, glass, ceramics, marble products, ores and minerals, industrial porcelain
