	A basic lead chromate pigment that ranges in shades from orange to red. First made in 1809 by Vauquelin, basic lead chromate is formed by heating lead chromate and sodium hydroxide solution. The color of chrome red, or chrome orange can vary from a brown-yellow to a brick-red color depending on particle size and to the ratio of lead oxide to lead chromate. It is stable in light but is not widely used because of its sensitivity to sulfur gases. Most often, chrome red is used as an anticorrosive base coats for steel.
