To quickly assess the difficulty of the text, read a short excerpt:
The result of the burning was an intensely hot iron whose composition could be varied at will. The commercial value of this invention is obvious. There are many processes and many emergencies where a very hot molten iron is invaluable, yet where it is difficult and expensive to get this heat by any known means. Take the case of a broken casting of some large machine that would in the ordinary course of repair have to be taken apart and shipped to the nearest forge to be welded. If, however, a d...efinite quantity of iron, heated to twice its melting point, can be made on the spot, it can be poured around this break without dismantling the machine. It will then form a welded union, much as though one were to put the butts of two candles together and pour hot tallow over the joint. The tallow would melt into the candles before it itself cooled, and join the two with a homogeneous substance. In order that the mechanical aspect of the thermit weld may be clear to the reader, a simple case of rail welding will be out- lined.
