or Bisk, among painters, a blue colour prepared from the lapis armenius.

Bice bears the best body of all bright blues used in common work, as house-painting, &c., but it is the palest in colour. It works indifferently well, but confines a little to sandy, and therefore requires good grinding. Next to ultramarine, which is too dear to be used in common work, it lies best near the eye of all other blues.
