Mohs Hardness Scale in Abrasive Blasting
WEBSetting aside wet blasting (mixing the media with water in a tank, or at the nozzle head) and dry ice blasting (generates no dust and is not abrasive), abrasive blasting that I am discussing here is indexed according to its hardness by the Mohs Scale. The Mohs Scale of mineral harness was created in 1812 by a German geologist Friedrich Mohs.
