Lead chromium green is a major coloring pigment of the paint industry, and the vast majority of green lacquers are formulated with this pigment. In addition, it is used in paints and plastics. Its application range is very similar to that of lead chrome yellow. Because there is chromic yellow in the composition, take care of its lead containing toxicity when applied. Lead chrome green contains iron blue and contains the oxidant lead chromate, so when dust encounters Mars with the possibility of autoignition, it is not prudent to dry, pulverize. The burnt lead chrome green completely loses the characteristics of a green pigment, transforming into a dark brownish yellow substance. In addition, while fabricating nitro paint, the rolling process did not directly roll with lead chromium green, whereas the process that was rolled after finishing with lead chromium green to prevent combustion while rolling the sheets.
