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: Price is also a factor: China mass-produces the stuff, and coloring agents like lead chromate are generally cheaper than organic pigments. A house painter in the early 20th century would show up to a job with two buckets-one for the paint substrate, one for the lead powder. The more lead he added, the better the paint, the higher the price.)Lead paint has other qualities that make it attractive to manufacturers. For one thing, it resists mildew, making it perfect for wood furniture and other surfaces likely to get wet. It's also anti-corrosive: Ship makers have historically applied a coating of lead paint, often containing the red mineral litharge, to the bottom of metal ships' hulls. (The Romans used lead paint, too-that's why the paint on some of their ruins is so well-preserved.)
Lead is a heavy metal that has historically been used to make paints, particularly in the form of lead white or lead chromate pigments. However, due to health and environmental concerns, the use of lead in paints has been banned or heavily regulated in many countries. Alternatives such as titanium dioxide and organic pigments are now commonly used instead.
All house paints sold in the United States and Canada are lead free. The only paints that contain lead are used in industrial applications and are should not be available for purchase to the general public. Lead is used in some artist oil whites, however, this is rare and the artist who uses them has to pay a premium to acquire them . Lead is not used in water based paints.

No, all paints are not lead free. In fact, there are only a few companies who manufacture lead free paints. Majority of the companies have some if not excessive amount of lead in their paints.
Lead is commonly used in heavy metal-based paints as a pigment and in radiation shields due to its high density and effectiveness in absorbing radiation.

Lead was commonly used in paints until harmful side effects, such as lead poisoning, were discovered. Lead poisoning can cause serious health issues, especially in young children and pregnant women. As a result, lead has been banned from use in paints in many countries.
Lead is a heavy metal that has been used by humans for thousands of years, primarily sourced from lead ore minerals such as galena (PbS). It is found naturally in the Earth's crust, where it is often extracted through mining. Historically, lead was utilized in various applications, including plumbing, paints, and batteries. Due to its toxicity, the use of lead has been regulated in many countries to mitigate health risks.
following are used in paint industry 1.Lead oxides{PbO,Pb3O4,PbO2} 2.Basic LEAD Carbonate{2PbCO3.Pb[OH]2 3.Lead Chromate[PbCrO4]
No modern paints contain lead. A number of colours of paint contained lead compounds, including red yellow and white paints. The compositions of the paints varied from manufacturer to manufacturer.
