“The first form of Sheffield Plate was arrived at by binding, with a brass wire, an ingot of silver to an ingot of copper which was hardened with about 25 percent brass alloy.”

“Each of the ingots was subjected to blooming into 155 mm square steel strips, and the resultant steel strips were subjected to wire rod milling.”

“Acquiring gold and silver was vital for coinage and, in the late Empire, for official payments in plate and ingots.”

“A bit farther on, glowing one-ton ingots of steel thunder down rollers to be pressed into thin sheets.”
