For what reasons was lead commonly used in paint?

The use of lead in paint primarily stemmed from its functional properties, particularly as a drying agent and for enhancing the durability of the paint. Lead compounds, such as lead-based driers, allowed paint to dry more quickly and create a tougher, more resilient coating, which was highly valued in both residential and commercial applications. The durability provided by lead also meant that fresh paint jobs would last longer, reducing the frequency of repainting.

While lead did have aesthetic appeal due to its ability to produce vibrant colors, its widespread use was mostly due to practical advantages related to drying time and longevity. These functional benefits made lead a popular choice for manufacturers looking to provide high-quality paints that could withstand various environmental conditions over time.
