Mohs Hardness Test: Obsidian, Quartz, Topaz & More

$100 per inch, that's pretty pricey. We tested the hardest materials we could find to show the power of water. We started with cutting obsidian and worked our way up the Mohs hardness scale. We got some of the top ten hardest things from quartz to topaz and man-made ceramic. We love our fans, and if you want to show love back you can do one of these things. Waterjet Knife blanks...
