The first written record of galvanizing describes how a French chemist named Melouin presented a method of coating iron by immersing it in molten zinc to the French Royal Academy in 1742. Sorel, another French chemist patented a process for coating iron with zinc after preparing it with 9% sulfuric acid followed by fluxing with ammonium chloride. Great Britain granted a patent for a similar process in 1837. By 1850, galvanizing had become a generally accepted practice for the protection of iron and steel with 10,000 tons of zinc per year used for the protection steel.
