This process consists in providing a molten bodyof iron ore on top of a molten charge of iron or steel andblowing a gas containing a reducing agent downwardly againstthe molten iron ore so that portions of the ore are carried be-low the surface of the charge of molten iron or steel and arethereby reduced to iron or steel. The gas employed is a non-oxidizing gas mixed with powdered carbonaceous material. Water HeaterPatent No. 1,255,835, issued to Hugh G. Shaug, of LosAngeles, California, shows a new form of gas
