Dow Chemical plant in South Charleston, West Virginia.
In 1746, John Roebuck revolutionized the production of sulfuric acid by introducing leaden condensing chambers, a method that became known as the lead-chamber process.12
Prior to this innovation, sulfuric acid was produced using small-scale glass or clay vessels. By substituting these with large, lead-lined chambers, Roebuck enabled the absorption of gases from burning sulfur into water on a much larger scale. This change significantly increased production capacity and drastically reduced costs, marking the beginning of large-scale industrial manufacturing for the chemical.21
