Smelting - History - Early Iron Smelting - LiquiSearch
These discoveries are significant for the history of metallurgy. Most early processes in Europe and Africa involved smelting iron ore in a bloomery, where the temperature is kept low enough so that the iron does not melt. This produces a spongy mass of iron called a bloom, which then has to be consolidated with a hammer.

Inhalation of respirable crystalline silica, metal fume, and gases and vapors from fluxes, binders, release agents ...
History of Metallurgy | 3MVET
The first use of iron involved the use of meteorite iron which is also the simplest use of iron as no smelting, involving the use of complex kilns with bellows, was needed. When furnaces were built that could achieve temperatures capable of smelting iron, the Iron Age began and iron replaced bronze as the principal material for tools and weapons.
Development of Smelting Reduction Processes for Ironmaking

Primitive Technology: Smelting Ore in a Draft Furnace
The draft furnace was built from termite mound clay reinforced with plant fibers. The advantage to a draft furnace is that there's no continuous labor involved, aside from feeding the fire with charcoal or wood fuel. The channel host sculpted his furnace from clay in a large cylinder, leaving an air vent tube — known as a tuyere — in the side.

Saugus Iron Works National Historic Site. The blast furnace was where the smelting process was started. 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, so named because liquid ...

Carbon plays a crucial role in iron and steel production. Carbon is often involved during the smelting process, and the higher temperature iron gets, the more carbon it will absorb. When iron takes on more and more carbon, it becomes harder and more brittle. Conversely, with less carbon, iron becomes more ductile and pliable.
