Right!Concept of an engine run on steam was not new. There was a huge demand for something to pump out water.You see where this is going. Deeper mines cut down on dust but flooding was a common problem because these were often located below the water line. Shallow mines were horribly dusty and not conducive to business … because you know, the laborers couldn’t breathe. They also realized that using coke (purified coal, which has a much less concentration of sulfur) as fuel would improve the quality of iron substantially.Mining flourished as an enterprise to cater to the increased demand of iron ore and coke. The resulting iron, known as pig iron, was brittle. You can think of the metallurgical bellow as a giant version of this.And this is a schematic of the whole process of smelting.Courtesy: Iron processingWhat has this got to do with steam engines, you ask?Charcoal is contaminated with sulfur, which in the course of smelting, blended with the iron ore. Charcoal, i.e., half burnt wood was used as the fuel, and bellows were used to deliver additional air to the fuel, thereby raising the rate of combustion. You heat the ore till the iron melts and then you pour it out.) What you needed was a sufficiently hot oven and fuel. Gee, haven’t we all learned in high school that James Watt invented the steam engine and spurred the Industrial Revolution!I, for one, am glad that you forgot that bit of history lesson, because the actual story is a much more fascinating account human enterprise, and an interplay between markets, technology, and capital.It all began with iron.You see, people had long known about iron ore, and as early as late 15th century, crude iron was being extracted by a process known as smelting.
