Excerpt from The Art of Galvanizing But why is it that zinc-dust acts in this peculiar manner, depositing zinc at a temperature several hundred degrees be low its melting point, and why is it that the comparatively cold zinc alloys itself to the iron or other metal when the mol ten zinc of the hot process fails to do so, or at best only does so in a cumbrous limited way? I can only answer these questions by giving you my own theory of the nature of zinc dust and of its action under the conditions of Sherard izing. This theory is quite new to the very best of my knowledge and was not published by me until quite recently;* it is founded on observed facts but is not entirely empirical, because so far it has seemed to satisfy all the theoretical tests to which I have been able to put it and, it answers a number of unexplained phen omena which I shall mention later.
