During the Han dynasty (202 BC – 220 AD), most, if not all, iron smelted in the blast furnace was remelted in a cupola furnace; it was designed so that a cold blast injected at the bottom traveled through tuyere pipes across the top where the charge (i.e. of charcoal and scrap or pig iron) was dumped, the air becoming a hot blast before ...
The Chinese are thought to have skipped the bloomery process completely, starting with the blast furnace and the finery forge to produce wrought iron; by the fifth century BC, metalworkers in the southern state of Wu had invented the blast furnace and the means to both cast iron and to decarburize the carbon-rich pig iron produced in a blast ...
Cornwall Iron Furnace was one of many ironworks that were built in Pennsylvania over a sixty-year period, from 1716 to 1776. There were at least 21 blast furnaces, 45 forges, four bloomeries, six steel furnaces, three slitting mills, two plate mills, and one wire mill in operation in Colonial Pennsylvania.
This used a blast furnace to make pig iron, which then had to undergo a further process to make forgeable bar iron. Processes for the second stage include fining in a finery forge. In the 13th century during the High Middle Ages the blast furnace was introduced by China who had been using it since as early as 200 b.c during the Qin dynasty.
Hopewell Furnace stove, 10-plate cooking model, with a lower firebox and upper oven for baking.
