Cast steel made by fusing in crucibles crude or scrap steel, wrought iron, and other ingredients and fluxes.

High Quality steel created by melting Blister Steel in a covered crucible using a coal fire. After the slag was removed, the resulting steel had consistent properties throughout. Process was superseded by Bessemer Process but crucible melting did not stop until after World War II.

(der) Tiegelstahl Wootz-steel is a steel which is formed in a processed called cemetation. This steel was produced as early as the 6th century AD in India. Another important centre for the production of crucible steel was Uzbekistan in the 10th century. Iron and carbon-rich material (e.g. plants, charcoal, etc) were placed in a →crucible and heated for a prolonged period of time. The carbon would form Carbonmonoxide (CO) and enrich the carbon content of the iron, thus forming the steel alloy.

steel made by the mixture of molten wrought iron, charcoal, and other substances in a crucible

Crucible steel describes a number of different techniques for making steel alloy by slowly heating and cooling pure iron and carbon (typically in the form of charcoal) in a crucible.
