Slate is a rock, so you won't find it listed on the Mohs Scale, because that scale of hardness applies to minerals. I'll go out on a limb though, and suggest that slate is probably around 2 to 3 or so, but this will be variable, depending on the quality of the slate, and degree of weathering, etc. Slate is a rock, so you won't find it listed on the Mohs Scale, because that scale of hardness applies to minerals.
Hardness testing is done by scratching one mineral with the other. To get the most accurate results, a sharp edge should be scratched against a smooth surface, on a small an area as possible. The scratch should not be conducted on a surface that is coated, chipped, or weathered, for it will give inaccurate results.
