The plastics industry contains some overlap, as most chemical companies produce plastic as well as other chemicals.

One of the first chemicals to be produced in large amounts through industrial process was sulfuric acid. In 1736, the pharmacist Joshua Ward developed a process for its production that involved heating saltpeter and allowing the sulfur to oxidize and combine with water. It was the first practical production of sulfuric acid on a large scale. John Roebuck and Samuel Garbett were the first to establish a large-scale factory in Prestonpans in 1749, which used leaden condensing chambers for the manufacture of sulfuric acid.
