History of the Cutlery Industry Museums Sheffield

Experiments by Benjamin Huntsman in the 1740s resulted in the crucible steel process. Blister steel was melted in a crucible with a purifying agent, which allowed the slag and impurities to be skimmed off and the carbon to be evenly distributed in the molten metal. The finished product could also be poured into moulds, to make any shape.
