Thwaites' Yellow

Under this name chromate of cadmium was introduced some few years back.
If well prepared, it is a fine soft powder of a very vivid light yellow
colour. The compound is too soluble, however, to be of value, its
washings even with cold water being continually tinged yellow. Hence it
turns green after a time, and becomes otherwise discoloured. Like
citron yellow and other chromates apt to assume a green cast, it should
only be employed, if at all, when compounded for foliage tints, &c. This
want of durability is to be regretted, for a good sample of cadmium
chrome is marked by exceeding beauty, unsurpassed for clearness and
purity by any other yellow.
