Ready-Mixed Paint

In 1867, a patent for the first prepared, or "ready-mixed" paint in the U.S. was granted to D.R. Averill, of Newberg, Ohio. The first recorded paint mill in America was reportedly established in Boston in 1700 by Thomas Child. In the nineteenth century, with the large-scale manufacture of linseed oil from the flax plant and pigment-grade zinc oxide were combined before the paint was marketed. Previously, home owners would mix their own paint from a base, oil, turpentine and pigments. It was Henry Alden Sherwin and partner Edward Williams who invested ten years in developing the commercial product and introduced it in 1880.
