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.

“Oh, you’ll love the sea. There’s something about it. The hot red dawn, the towering sails, the wake on a tropical night. Oh, you’ll love it all. It’s a glorious kind of world. I couldn’t live without it.”

“Once more unto the breach, dear friends, once more,
Or close the wall up with our English dead.
In peace there’s nothing so becomes a man
As modest stillness and humility,
But when the blast of war blows in our ears,
Then imitate the action of the tiger.
Stiffen the sinews, conjure up the blood,
Disguise fair nature with hard-favoured rage.”
—William Shakespeare (1564–1616)
