CHAP. 24. (11.)—THE SCORIA OF COPPER.
The scoria, too, of copper is washed in the same manner; but
the action of it is less efficacious than that of copper itself.
The flower, too, of copper [Note] is also used in medicine; a substance
which is procured by fusing copper, and then removing it into
another furnace, where the repeated action of the bellows
makes the metal separate into small scales, like the husks of
millet, and known as "flower of copper." These scales are
also separated, when the cakes of metal are plunged into
water: they become red, too, like the scales of copper known
as "lepis," [Note] by means of which the genuine flower of copper
is adulterated, it being also sold under that name. This last is
made by hammering nails that are forged from the cakes of
metal. All these processes are principally carried on in the
furnaces of Cyprus; the great difference between these substances
being, that this lepis is detached from the cakes by
hammering, whereas the flower falls off spontaneously.
