obtained by the action of heat on mixtures of earthy or metallic bases
with cobalt. They are divisible into three classes--the stannic cerulian
blue, the aluminous cobalt blues, and the siliceous smalts. Of these,
the first possesses the least depth; the second hold a middle position;
while the third are marked by exceeding richness. Although not to be
ranked with ultramarine, the stannic and aluminous blues may be
described as durable, or at least as durable rather than semi-stable.
There are, as we have before observed, different degrees of permanence,
and the blues in question are not readily affected. With regard to
smalts, they are, as artist's pigments, inferior in stability to other
blues of cobalt.
