Excerpt from The Penny Cyclopedia of the Society for the Diffusion of Useful Knowledge, Vol. 23: Stearic Acid-Tagus

In the opinion of Mr. Brande, the quantity of carbon in the above analyses is somewhat underrated; and be has found that when the carbon has fallen short of one per cent, the steel was deficient in hardness; and when it has exceeded this proportion, the dies have split or not stood their work. He states, at the same time, that minute quan tities of other bodies appear to influence the quality of steel; and that unless it contain phosphorus it cannot be depended on for the manufacture of dies in coining.
