    Top 10 Mohs Scale Degrees of Hardness Talc Mohs Hardness: 1 – Talc (Absolute Hardness: 1) In case you were wondering, yes, it really is Talc the mineral that is crushed into powder to form talcum powder Minerals for you and your baby Tweet; Share on Tumblr; Like this: Like Loading theverybesttop10 Post navigation The Top 10 Heaviest Elements in the Entire Known Universe The hardness of talc, the softest of minerals, defines the value of 1 on the scale (Any mineral with a value less than 2 can be scratched by a fingernail) When scraped on a streak plate, talc produces a white streak; though this indicator is of little importance, because most silicate minerals produce a Talc WikipediaTalc is green, grey, brown, , white, or colorless it is translucent with pearly luster it is the softest known mineral and has a hardness of 1 on the Mohs hardness scale Similar to the Micas, Talc is a monoclinic mineral with a sheet structure talc has perfect cleavage ;this features is responsible for Talc's extreme softness its soapy, greasy feel and its value as a high temperature Talc Lidoma Mineral Industrial CoThe Mohs Scale is shown below, using commonly known minerals to represent each degree of hardness: Talc; Gypsum; Calcite; Fluorite; Apatite; Feldspar; Quartz; Topaz; Corundum; Diamond; While a reference set of the above minerals may be used to test the hardness of an unknown mineral, such a set is rarely used in actual practice; particularly because diamond is rather expensive to be used as an Mohs Hardness Test Oakton Community College  Talc has a Mohs hardness of 1, while diamond has a hardness of 10 The Mohs scale is only one hardness scale It is useful in mineral identification, but cannot be used to predict the performance of a substance in an industrial setting About the Mohs Scale of Mineral HardnessMohs Scale of Mineral Hardness ThoughtCo
