The Mohs scale measures the relative hardness of minerals, but testing its resistance to scratching. On a scale of 1-10, talcum is the softest mineral at 1, while diamond is the hardest at 10. It was named after Frederich Mohs, who developed this scale in 1822, and is extensively used by field geologists and gemmologists.
This infographic gives you a handy chart that arranges 60 common metals in order of hardness. The chart also indicates the uses of each metal, and categorizes them into 6 metal families. A great chart to download and print!
