Bice, Blue Bice, Iris, Or Terre Bleu, is sometimes confounded with the above copper blues; but the true bice is said to be prepared from the lapis Armenius of Germany and the Tyrol, and is a light bright hue. The true Armenian stone of the antients was probably the lapis lazuli of later times, and the blue prepared therefrom the same as our ultramarine. Pale ultramarine may well supply the place of this pigment, but copper blues substituted for this pigment are to be avoided.
Ground smalts, blue verditer, and other pigments, have passed under the name of bice; which has, therefore, become a very equivocal pigment, and its name nearly obsolete: nor is it at present to be found in the shops, although much commended by old writers on the art.
