in 1844, government surveyors were exploring rugged, lake-filled terrain near negaunee, michigan, when they noticed their compasses swung erratically in certain areas. it did not take long to determine why: ancient precambrian rock layers in the area were laced with bands of iron ore.

Ancient Iron Production - Wikipedia

Ancient iron production - Wikipedia

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 for study. the size,

the earliest piece of iron production debris at this site, and indeed anywhere, is a heavily corroded lump about 3 cm wide, originally dated to the old hittite period (stratum iiib), but later assigned to the old assyrian colony period (stratum iiic) (akanuma 2007, pp. 125–127). the heavily corroded microstructure of the lump consists of dendrites of what is either corroded iron metal or wüstite, along

Iron Processing | Britannica

Iron processing | Britannica

by the middle of the 16th century, blast furnaces were being operated more or less continuously in southeastern england. increased iron production led to a scarcity of wood for charcoal and to its subsequent replacement by coal in the form of coke—a discovery that is usually credited to abraham darby in 1709. because the higher strength of coke enabled it to support a bigger charge, much larger furnaces became possible, and weekly outputs of 5 to 10 tons of pig iron

in 1700 the iron industry was in a downward trajectory. ironworkers required charcoal to smelt the iron ore or known in the 18th century as ‘ironstone’ in their furnace. charcoal however was in short supply as the wood required to make charcoal was expensive. this posed an industrial problem. in the course of a

Why Was Iron So Important During The Industrial Revolution?

Why Was Iron so Important During the Industrial Revolution?

iron processing facilities were small and only handled small quantities of iron at a time, making iron production limited in output and expensive. prior to the industrial revolution, the process of iron production involved combining and melting iron with other sources of fuel, primarily charcoal.
