Is The Commercial Name Of Green Lakes Prepared From Sulphate Of

copper. These vary in hue and shade, have all the properties of the

common non-arsenical copper-greens, and, not being subject to change of

colour by oxygen and light, stand the weather well, and are excellent

for the use of the house-painter, &c. Having a tendency to darken and

blacken by time and foul air, they are not eligible in the nicer works

of fine art.

Another Mineral Green adopted in Germany as a substitute for the

poisonous Schweinfurt green, is composed of chromate of lead, carbonate

of copper, oxide of iron, and chalk. Valueless for the palette, it has

not the beauty of Schweinfurt green, but is recommended as being free

from arsenic. It is not, however, altogether harmless, and should not

be used in confectionery or the like.
