Read More30-09-2016 · Calcite, as you've discovered, is very, very different from quartzite. It's not suitable for a kitchen, IMHO, unless you are prepared to take a lot of extra care (including regular sealing) to prevent etching, scratching, and staining. If you actually cook, and you have small children, it's not a very practical choice.
Read MoreMohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist.Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc but not calcite, which is even harder.
