  1. Mica

    The mica group of sheet silicate minerals includes several closely related materials having close to perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms. The word "mica" is derived from the Latin word mica, meaning "a crumb", and probably influenced by micare, "to glitter".

Sample Sentences & Example Usage

  1. Primo Levi:

    For me chemistry represented an indefinite cloud of future potentialities which enveloped my life to come in black volutes torn by fiery flashes, like those which had hidden Mount Sinai. Like Moses, from that cloud I expected my law, the principle of order in me, around me, and in the world. I would watch the buds swell in spring, the mica glint in the granite, my own hands, and I would say to myself: I will understand this, too, I will understand everything.
