Puddling (metallurgy) in the context of "Industrial revolution"

The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a transitional period of the global economy toward more widespread, efficient and stable manufacturing processes, succeeding the Second Agricultural Revolution. Beginning in Great Britain around 1760, the Industrial Revolution had spread to continental Europe and the United States by about 1840. This transition included going from hand production methods to machines; new chemical manufacturing and iron production processes; the increasing use of water power and steam power; the development of machine tools; and rise of the mechanised factory system. Output greatly increased, and the result was an unprecedented rise in population and population growth. The textile industry was the first to use modern production methods, and textiles became the dominant industry in terms of employment, value of output, and capital invested.

Many technological and architectural innovations were British. By the mid-18th century, Britain was the leading commercial nation, controlled a global trading empire with colonies in North America and the Caribbean, and had military and political hegemony on the Indian subcontinent. The development of trade and rise of business were among the major causes of the Industrial Revolution. Developments in law facilitated the revolution, such as courts ruling in favour of property rights. An entrepreneurial spirit and consumer revolution helped drive industrialisation.

Many significant developments in the history of science and technology in China took place during the Han dynasty (202 BCE – 220 CE).

The Han period saw great innovations in metallurgy. Following the inventions of the blast furnace and cupola furnace during the Zhou dynasty (c. 1046 – 256 BCE) to make pig iron and cast iron respectively, the Han period saw the development of steel and wrought iron by use of the finery forge and puddling process. With the drilling of deep boreholes into the earth, the Chinese used not only derricks to lift brine up to the surface to be boiled into salt, but also set up bamboo-crafted pipeline transport systems which brought natural gas as fuel to the furnaces.

A finery forge is a forge used to produce wrought iron from pig iron by decarburization in a process called "fining" which involved liquifying cast iron in a fining hearth and removing carbon from the molten cast iron through oxidation. Finery forges were used as early as the 3rd century BC in China. The finery forge process was replaced by the puddling process and the roller mill, both developed by Henry Cort in 1783–4, but not becoming widespread until after 1800.

Peter Cooper (February 12, 1791 – April 4, 1883) was an American industrialist, inventor, philanthropist, and politician. He designed and built the first American steam locomotive, the Tom Thumb, founded the Cooper Union for the Advancement of Science and Art, served as its first president, and stood for election as the Greenback Party's candidate in the 1876 presidential election.

Cooper began tinkering at a young age while working in various positions in New York City. He purchased a glue factory in 1821 and used that factory's profits to found the Canton Iron Works, where he earned even larger profits by fabricating machinery such as the Tom Thumb. Cooper's success as a businessman and inventor continued over the ensuing decades, and he became the first mill operator to successfully use anthracite coal to puddle iron. He also developed numerous patents for products such as gelatin and participated in the laying of the first transatlantic telegraph cable.

Henry Cort (c. 1740 – 23 May 1800) was an English ironware producer who was formerly a Navy pay agent. During the Industrial Revolution in England, Cort began refining iron from pig iron to wrought iron (or bar iron) using innovative production systems. In 1784, he obtained a patent for an improved version of Peter Onions's puddling process, for refining cast iron, although its commercial viability was only realised in the 1790s, through further innovations introduced by Richard Crawshay and Homfray of the Cyfarthfa Ironworks in Merthyr Tydfil.
