Mineral Hardness Test Kit - Education Set oversized t-shirt men the feldspar crystals inside theseDescription: This Mohs Hardness Test Kit is designed for straightforward mineral identification using scratch testing. By comparing a specimen against known hardness points on the Mohs scale, you can quickly narrow down what it could be based on resistance to scratching. A key feature is the streak plate, which reveals the true powdered color of a mineraloften more reliable than surface color, especially for metallic specimens. Used together, hardness
