    Palabora mine (Foscor open pit; PMC mine)

    4.76 x 2.92 x 0.07 inches (12.1 x 7.44 x 0.18 cm)


    Currently still mined commercially in Russia, South Africa, China and Brazil, the mineral Vermiculite undergoes significant expansion when heated. In fact, the name comes from the Latin vermiculare, meaning "to breed worms" for the manner which it exfoliates when heated. This golden specimen resembles a thin sheet of Mica and is a nice freeform example of the layered material. Vermiculite serves as a component in fireproofing products, and the mineral has been associated with asbestos.
