Why Use Lead in Paint?

Great article on Slate.com about why manufacturers use lead paint. To sum it up:

“Because it’s bright, durable, flexible, fast-drying, and cheap. Paint manufacturers mix in different lead compounds depending on the color of the paint. Lead chromates, for example, can enhance a yellow or orange hue. Municipal workers often use lead paint because it resists the color-dimming effects of ultraviolet light: The double yellow line in the middle of the road? That’s loaded with lead. Paint manufacturers also add lead and other heavy metals to make paint stick better instead of flaking off. Price is also a factor: China mass-produces the stuff, and coloring agents like lead chromate are generally cheaper than organic pigments.”
