Why can a diamond scratch chalk?
No. Hardness is measured on the Mohs Scale, named after German Friedrich Mohs. On this scale Talc (the softest) measures 1, while Diamond (the hardest) measures 10. Glass has a Mohs' scale hardness of around 5.5, so anything above that will have the ability to scratch glass. For example, quartz (Mohs 7), hardened steel (Mohs 8), corundum (rubies and sapphires, Mohs 9),or diamond (Mohs 10). The Mohs scale is purely an ordinal scale, expressing relative hardness in a simplistic way. Carborundum (Mohs 9) is twice as hard as Topaz (Mohs 8), but diamond (Mohs 10) is four times harder than arborundum.
