History
Filings are mostly a byproduct of the grinding, filing, or milling of finished iron products, so their history largely tracks the development of iron. For the most part, they have been a waste product.
Iron filings have some utility as a component in primitive gunpowders. In such a fine powdered form, iron can burn, due to its increased surface area.
In modern electronics, some transformers have iron powder cores.

Famous quotes containing the word history:
“The history of American politics is littered with bodies of people who took so pure a position that they had no clout at all.”
—Ben C. Bradlee (b. 1921)
“All history attests that man has subjected woman to his will, used her as a means to promote his selfish gratification, to minister to his sensual pleasures, to be instrumental in promoting his comfort; but never has he desired to elevate her to that rank she was created to fill. He has done all he could to debase and enslave her mind; and now he looks triumphantly on the ruin he has wrought, and say, the being he has thus deeply injured is his inferior.”
—Sarah M. Grimke (1792–1873)
“Every literary critic believes he will outwit history and have the last word.”
—Mason Cooley (b. 1927)
