    The lead chamber process was an industrial method used to produce sulfuric acid in large quantities. It has been largely supplanted by the contact process. In 1746 in Birmingham, England, John Roebuck began producing sulfuric acid in lead-lined chambers, which were stronger and less expensive, and could be made much larger, than the glasscontainers which had been used previously. This allowed the effective industrialization of sulfuric acid production and, with se
