John "Iron-Mad" Wilkinson (1728 – 14 July 1808) was an English industrialist who pioneered the manufacture of cast iron and the use of cast-iron goods during the Industrial Revolution. He was the inventor of a precision boring machine that could bore cast iron cylinders, such as cannon barrels [ 1 ] and piston cylinders used in the steam ...
By 1776, up to 80 iron furnaces throughout the American colonies were producing about as much iron as Britain itself. If one estimate of 30,000 tons of iron each year is accurate, then the newly formed United States was the world's third-largest iron producer, after Sweden and Russia. Notable pre-19th-century iron furnaces in the US
The process of converting pig iron into wrought iron (also known as bar iron) was at that time carried out in a finery forge, which was fuelled by charcoal.Charcoal was a limited resource, but coal, more widely available, could not be used because the sulphur in coal would adversely affect the quality of the wrought iron.
His products were all of cast iron, though his immediate successors attempted (with little commercial success) to fine this to bar iron. [93] Bar iron thus continued normally to be made with charcoal pig iron until the mid-1750s. In 1755 Abraham Darby II (with partners) opened a new coke-using furnace at Horsehay in Shropshire, and this was ...

Most cast iron was refined and converted to bar iron, with substantial losses. Bar iron was made by the bloomery process, which was the predominant iron smelting process until the late 18th century. In the UK in 1720, there were 20,500 tons of cast iron produced with charcoal and 400 tons with coke.
