what is highest on the mohs scale
To answer this question, itâs important to first talk about the Mohs scale. The Mohs scale characterizes the range of hardness that different minerals contain. Specifically, it identifies scratch resistance of various minerals, through the ability of a harder material to scratch a softer material. The scale ranges from 1-10, 1 being the softest, and 10 being the hardest. To give you an idea, Diamonds are considered a 10, while Talc is considered a 1. Volcanic glass is right in the middle, with a 5. Where Does Soapstone Fall on the Scale? When put on the Mohs Scale, traditional soapstone is softer due to higher talc content. But even soapstone has a range. It could be a 2.5 on the Mohs scale, like Mariana and Barroca. Churchill, our most popular variety, sits at a 3. Or, it could be as high as a 5 on the scale, like Noir, Sabon, and PA. The hardness of soapstone can depend on its parent material, i.e., its makeup.
