This is an original 1890 one-page and a half (1 page, double-sided) article about the Pyro-engraving tools, made by M. Manuel Perier, a Frenchman. Mr. Perier began his experiments with small soldering irons heated by gas, and afterwards substituted for these a platinum wire kept incandescent for these a platinum wire kept incandescent with the aid of the electric current. The system of thermo-cautery devised by Dr. Paquelin gave M. Perier the clue to the proper solution of the problem for which he was seeking--namely, to be able to maintain for an indefinite period, at a uniform temperature, the incandescent point, or tracer, with which the carbonization of the object to be decorated is effected. The Pyrogravure apparatus as thus modified is shown in fig. 1. It consists of three principal parts: the air reservoir, the carburetor, and the incandescent stylus. Fig. 2 represents the artist at work with a Pyrogravure apparatus.
