  • A rare mineral, vaterite, acts as a shock absorber …

    Birds' eggshells are primarily composed of calcite, an abundant polymorph of calcium carbonate (CaCO 3 ). However, the eggshells of some species are coated with spherules of vaterite, a rare and thermodynamically unstable polymorph of CaCO 3, the function of which remains unknown. Here we experimentally test the mechanical and physiological effects of the vaterite coating on eggshells of ...

    The Mohs Hardness Scale was developed in 1812 by a German geologist and mineralogist, Friedrich Mohs to determine the relative hardness of a mineral as a comparison to another mineral. For example, the scale begins with the softest material, talc. All materials above talc have the ability to scratch talc. The second material is gypsum, and since talc is below gypsum, talc is softer and thus ...
