The blowing cylinder for blast furnaces was launched in 1760 and the primary blowing cylinder manufactured from solid iron is believed to be the one used at Carrington in 1768 that was designed by John Smeaton.
The decarburized iron, having a better melting point than solid iron, was raked into globs by the puddler.
