Industrial Patterns 12: Steelpunk

A Bessemer Converter is a grand metal pot in which steel used to be made, before more modern techniques made it obsolete. Cold air is injected into its lake of molten metal so that the impurities can be burned off. This burning process creates a fabulous eruption of flame and sparks, and what is left is made into steel. This little sketch shows part of the base of a Bessemer converter. I wish I could have seen one in action. The patterns on the right of the drawing are not part of any machine but were made in steel-clad Photoshop.
