Kemondo Iron Age Sites or KM2 and KM3 are Early Iron Age complex industrial archaeological sites in Kemondo ward, Bukoba Rural District, Kagera Region, Tanzania, excavated by a team led by archaeologist Peter Schmid in the late 1970s and 1980s. The excavations aimed at better understanding the iron smelting process and its ritual aspects in ...
A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into ...
A water jacket furnace could be used to reduce non-ferrous oxide ores mixed with coke, to produce metal, but its main use was smelting the more common sulphide ores. The feedstock was the ore, coke and fluxes. When smelting lead sulphide ores, a water jacket furnace produces molten lead and slag. Lead and silver often occur in the same ore body.
Iron oxide becomes metallic iron at roughly 1250 °C (2282 °F or 1523 K), almost 300 degrees below iron's melting point of 1538 °C (2800 °F or 1811 K). [ 5 ] Mercuric oxide becomes vaporous mercury near 550 °C (1022 °F or 823 K), almost 600 degrees above mercury's melting point of -38 °C (-36.4 °F or 235 K), and also above mercury's ...
Waterfall on the River Einion at Dyfi Furnace. A mill race leads from the top of the waterfall to power the breastshot waterwheel. The site for Dyfi Furnace was chosen downstream of the waterfall on the River Einion to take advantage of the water power from the river and charcoal produced from the local woodlands, with the iron ore being shipped in from Cumbria via the Afon Dyfi.
Located along State Route 278, approximately 5 miles (8.0 km) northeast of the village of Zaleski, [1] it is one of two extant iron furnaces in Vinton County. Between 1854 and 1874, the furnace was used to smelt iron ore, using coal or charcoal for fuel. It is a rectangular structure, built of sandstone and shaped like a truncated pyramid. [2]
Flake hammerscale is produced in large quantities during multiple stages of the smithing process. To create the pure iron necessary for forging, a smith must first purify the iron ore. The smelting of ore creates a "bloom", a porous mixture of slag and metal. The smith then repeatedly heats and hammers the bloom to remove impurities.
Iron smelting—the extraction of usable metal from oxidized iron ores—is more difficult than tin and copper smelting. While these metals and their alloys can be cold-worked or melted in relatively simple furnaces (such as the kilns used for pottery ) and cast into molds, smelted iron requires hot-working and can be melted only in specially ...
