Part one: Emergence and evolution of flexible heating elements The arrival of these devices in the very last years of the 19th century is linked to the convergence of several technological developments: - The development of medical science, and the study of the effects of heat on the treatment of certain diseases (particularly rheumatism and neuralgia) - The weaving of asbestos threads in braids around a heating wire - The progress of wire drawing techniques, making it possible to produce threads with small diameters, to the order of a tenth of a millimeter - Improvement of refining processes for nickel and its alloys, making it malleable. - The development of domestic electrical distribution. Weaving asbestos, which was named “bright flax” or “salamander wool” by old alchemists, had been known of since ancient times.
