This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1869 edition. Excerpt: ... consists in treating the iron castings with vegetable oil at an elevated temperature, so as to produce upon the metallic surface a skin of oxide, which, in combination with the decomposed organic substance, gives the desired color and appearance. The castings, when finished and cleaned, are carefully covered with a liquid oil all over their surface, and particular attention is paid to the removal of all surplus oil, so as to leave only an extremely thin coating upon the metallic surface. In that state the iron casting is ready for the oxidizing process. It is brought into a stove heated to the temperature which decomposes the oil without charring it. This temperature is the same which will impart to cast iron a blue tint when exposed to it, with a clean metallic surface. At this temperature, therefore, the double process of oxidization of the iron and of decomposition of the oil takes place simultaneously, and the castings are covered with a brown coating of oxide, which remains fixed to the surface with great durability, protecting the iron from further oxidation, and having the same lustre and metallic appearance as real bronze. The durability of this 'bronzing' is very considerable, and even those spots which, by constant wear, lose their superficial coating of oxide after some time, maintain the original brown color, since a new coat of brown oxide of iron is formed under the influence of the atmosphere, which makes the difference between the injured parts and those which have maintained their original color scarcely perceptible. Mr. Tucker's bronzes are, of course, much cheaper than real bronze articles, and they also compete to advantage with imitation bronze, over which latter material they also present the advantage of greater durability...
