Ancient iron production refers to iron working in times from prehistory to the early Middle Ages where knowledge of production processes is derived from archaeological investigation. Slag, the byproduct of iron-working processes such as smelting or smithing, is left at the iron-working site rather than being moved away with the product.It also weathers well and hence it is readily available

Ellingham diagram Wikipedia

Ellingham diagrams are a particular graphical form of the principle that the thermodynamic feasibility of a reaction depends on the sign of ΔG, the Gibbs free energy change, which is equal to ΔH − TΔS, where ΔH is the enthalpy change and ΔS is the entropy change.. The Ellingham diagram plots the Gibbs free energy change (ΔG) for each oxidation reaction as a function of temperature.

Hurstwic: Iron Production in the Viking Age

Iron Production in the Viking Age. Elemental iron formed in the upper part of the furnace dropped down and collected in the slag bowl. If the liquid slag rose to a high enough level to block the air from the tuyere, the iron making process could be impacted. The level of the slag (and the falling of the iron) could be monitored, both by the

The interaction of iron and erythropoietin

Our model of iron and erythropoietin shows stem cells maturing along the erythroid line to form BFU-E's (Figure 3). At this point iron is needed for the production of new hemoglobin. Erythropoietin promotes the maturation of BFU-E's into CFU-E's and subsequently into mature erythrocytes.

Coke (fuel) Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low
