Cimolite (cimolian earth) is a soft, earthy, clayey mineral, of whitish or greyish colour named from Cimolos or Argentiera, one of the Cyclades, where it is still to be found. It is a fine powder, and effervesces with acids. In classical times it was used as a detergent, as a soap for cleaning delicate fabrics, and by the bath-keepers.
