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.

Famous quotes containing the words hot and/or blast:
“We should be careful to get out of an experience only the wisdom that is in it—and stop there; lest we be like the cat that sits down on a hot stove-lid. She will never sit down on a hot stove-lid again—and that is well; but also she will never sit down on a cold one anymore.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“When autonomy is respected, the two-year-old does not carry this unfinished task into later stages of growth. In adolescence, the youngster will again concentrate on independence, but he won’t have to blast the roof off the second time around if it is already well established.”
—Dorothy Corkville Briggs (20th century)
