Permanent Painting

facturer called it Chinese white. The description will be found under the head of zinc white.

CHROME GREEN, LIGHT, MEDIUM AND DARK

These greens are unfortunately named, because although there is some chromium in their composition from the chromate of lead which they contain, they are strictly speaking, not pure chrome greens, such as guignet or viridian green. Chrome greens are essentially a double precipitate of chrome yellow and Prussian blue, and vary in shade according to the percentage of yellow or blue which they may contain. These colors may work very well and dry very well, but have the combined defects of chrome yellow and Prussian blue. Assuming that the color is properly made, it is fairly permanent to light, has tremendous tinting power, but is acted upon by sulphureted hydrogen, and even when not subjected to the action of any gas, it loses its brilliancy within a very few years. It is not recommended as a necessary color and can be very well omitted.
