His iron workers may have contributed to his discovery. According to Kelly's
biography, in 1854 he hired Chinese iron workers through a New York
teahouse. Historian of metallurgy Donald Wagner notes that a similar process
was already extant in China, and that Kelly's Chinese iron workers were
likely familiar with how molten cast iron behaved under an air blast. The
engineer William Phillips, after a trip to Eddyville, wrote in 1899 that "
the Chinese had refined iron by blowing air into it a great many years ago,
and I have thought that Kelly, in asking for Chinese laborers, would
naturally require the services of those who had some knowledge of the iron
business." |
