BESSEMER-THOMAS PROCESS

Prior to the introduction of the blast furnace, iron was reduced as solid metal by heating a mixture of iron ore and charcoal in a hearth type furnace. To produce structural metals, the iron was heated in charcoal fire for sufficient time. Then it was cooled and hardened by cooling water. In this way the steel was produced.

Blast Furnace (U.S. National Park Service)

In 1646, the original blast furnace roared to life, lit with a 3000 degree fire that was kept burning 24 hours a day for months at a time. The blast furnace is where bog ore was smelted to create cast iron "pig" bars. To do this, three types of raw materials were brought over the charging bridge and loaded into the chimney of the furnace.
