The hardness of my fossil is over a 5 on the hardness scale because it does cut glass. It's so heavy just for a small chunk, has shale like layers, sorta chalky, and has the most remarkable glittery dust of green copper red gold blue sparkles to it but very small it's best to use a magnifier to get good close up look. It's black in some areas as if it we're magma or from lava flow. What is the glittery part in fossils?

Using mohs hardness scale test for selecting blasting media?
Scuter posted a topic in Questions & Answers
I had received a rock hardness tester kit and was not shore what to do with it. Through some research I was able to find that the testing was known as a mohs test, and this test classifies rock in a 1 to 10 scale. This is nominally used for minerals, but what I was cureus about is using this scale for matrix uncovering fossil prep. If this is possible I wish to use this identification poses for selecting a blasting media. Duos anyone know if this is possible?
