Mica [Noun.]

Any of a group of minerals characterized by highly perfect cleavage, the tendency of crystalline materials to split along definite crystallographic structural planes, which explains why it readily separates into very thin leaves. It is used in electric conductors, roof insulation, house paint, soil conditioner, cosmetics and toothpaste.

‘Wholly, holly, signal, signing,
Same, examining, but mining,
Scholar, vicar, and cigar,
Solar, mica, war and far.’
– Gerard Nolst Trenité, The Chaos

  1. This is known as “Lone Mountain,” and I have climbed to the top of it. Lone mountain is not entirely alone, but merely separated from several other plateaus of its type in the region that it occupies in northwestern Oklahoma, an area that at one point in time was the location of an inland sea.

    Lone Mountain and its companions are topped with a surface that is almost entirely composed of micah, lending them the name of the “Gloss” or “Glass” Mountains.
