In the era of commercial wrought iron, blooms were slag-riddled iron castings poured in a bloomery before being worked into wrought iron. In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than 36 in 2 (230 cm 2).

The converting process occurs in a converter. Two kinds of converters are widely used: horizontal and vertical. Horizontal converters of the Peirce-Smith type (which are an improvement of the Manhès-David converter ) prevail in the metallurgy of non-ferrous metals. Such a converter is a horizontal barrel lined with refractory material inside.
