Hot blast refers to the preheating of air blown into a blast furnace or other metallurgical process. This has the result of considerably reducing the fuel consumed in the process. This was invented and patented for iron furnaces by James Beaumont Neilson in 1828 at Wilsontown Ironworks in Scotland, but was later applied in other contexts, including late bloomeries.

“Too often when you thought you’d be showered with confetti
What they flung at you was a plate of hot spaghetti
You’ve put your fancy clothes and flashy gems in hock
Yet you pause before your father’s door afraid to knock”
