Printable Mohs Hardness Scale - Web the mohs' hardness scale originally ranged from 1 (soft) to 10 (hard) but has recently been expanded to 15 by ridgeway to include synthetic abrasives. The scale is not a linear scale, but somewhat arbitrary. This method is especially useful for identifying minerals in the field because you can test minerals against some very common objects (fingernail, a penny, a nail). Web the mohs hardness scale is based on ten minerals of different hardness, divided into ten levels from low to high: The mohs scale was invented in 1812, by the german mineralogist friedrich mohs. Web mohs hardness tables hardness number original scale modified scale 1 talc talc 2 gypsum gypsum 3 calcite calcite 4 fluorite fluorite 5 apatite apatite 6 orthoclase orthoclase 7 quartz vitreous silica 8 topaz quartz or stellite 9 corundum topaz 10 diamond garnet 11 *** fused zirconia 12 *** fused zirconia 13 *** silicon carbide 14 *** boron.
The scale isn’t perfect, but it’s a great tool for quick identification of rocks in the field. You can move the markers directly in the worksheet. Web gemstone hardness is a measure of how difficult (or easy) it is to scratch the surface of the gemstone. What a scratch test is and why a scratch test is performed.
