Note 185 — Chapter IV · LETTER-FOUNDING AS AN ENGLISH MECHANICAL TRADE. 1477–1830.
Reading edition
Iron does not appear to have continued much longer as a staple ingredient of English type-metal. There was, however, no rule as to the composition of the alloy. The French type-metal at the beginning of the eighteenth century was notoriously bad, and drove many printers to Frankfort for their types, where they used a very hard composition of steel, iron, copper, brass, tin and lead.
