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.

“A boy not beautiful, nor good, nor clever,
A black cloud full of storms too hot for keeping,
A sword beneath his mother’s heart— yet never
Woman bewept her babe as this is weeping.”

Mend measles, nag noses, blast blisters
And all day waste wordful girls
And war-boys, and all day
Say “Oh God!””
