Century Dictionary and Cyclopedia
nwootzThe name given to steel made in India by fusing iron with carbonaceous matter. This is done in small crucibles holding a pound or two of the iron, and the wood selected to furnish the carbon to the metal is always that of Cassia auriculata, which is cut into small pieces, the same being done with the iron, and the whole covered by one or more green leaves, usually of a species of Convolvulus, the crucible being then covered with a lid of clay. A number of these crucibles are placed together in a hole dug in the ground, and heated in a charcoal-fire urged by a pair of bellows made of ox-hide, the blast being kept up for three or four hours. The steel thus obtained is hard in temper, and requires much care in working. This is the oldest method of making steel of which anything definite is known, having been in use, without change, for an indefinite length of time, and being, as generally believed, original with the Hindus.
