Because it is harder to obtain English copper during the Napoleonic Wars due to embargoes, duties, and travelling difficulties, the demand from American shipbuilders and craftsmen, prospering during the war, increases. Harmon becomes more interested in the manufacture of American copper, especially with the outbreak of the War of 1812. Works with Paul Revere, Robert Fulton, and other American merchants and manufacturers to find solutions for the shortage and produce quality copper.
