Molten cast iron was poured into a stone basin in a reverberatory furnace and exhaust gasses from a hot fire were run over the top of the basin.
The specification of the invention will be comprised in a few words, as it will only set forth that a reverberatory furnace being built of a proper construction, the pig or cast iron is put into it, and without the addition of anything else than common raw pit coal, is converted into good malleable iron, and, being taken red-hot from the reverberatory furnace to the forge hammer, is drawn out into bars of various shapes and sizes, according to the will of the workmen.
Then the brothers Cranege, in 1766, adopted the reverberatory or air furnace, in which they placed the pig or cast iron, and without blast or the addition of anything more than common raw pit-coal, converted the same into good malleable iron, which being taken red hot from the reverberatory furnace to the forge hammer, was drawn into bars according to the will of the workman.
He first set up his crucible upon the bridge of the reverberatory furnace used for melting pig-iron, and filled it with a mixture carefully compounded according to the formula of the books.
