The term ‘wrought iron’ tends to be used some authors for all ancient iron. However, before the introduction of the indirect process, such use is a tautology in that all iron was wrought (wrought means forged). Also the mechanical properties of bloomery iron and wrought iron are different in that bloomery iron tends to contain variable but higher amounts of carbon than refined cast iron. Whereas, wrought iron tends to have a much higher volume of slag inclusions. Therefore, the term wrought iron should be restricted to forged refined cast iron.
