The Colouring Bronzing And Patination Of Metalsl !LINK!
New York: Van Nostrand Reinhold Company, 1983. 4to. 372 pages. Color photographs. Cloth, dust jacket. A very good copy with shelfwear; slight darkening around cover and pages. Item #405519 ISBN: 0442231709 FIRST EDITION. "The techniques of metal colouring, bronzing and patination are assuming a new importance in contemporary fine metalwork and design. Richard Hughes and Michael Rowe have assembled and tested the recipes included in this book, which is the most comprehensive work on the subject currently available, an essential reference and sourcebook for practitioners and all those involvoved in sculpture, architecture, designs and the decorative arts. It brings together hundred of recipes and treatments previously scattered in a variety of old books and technical papers, and provides the artist-craftsman with a very wide range of coloured finishes" (the publisher).
There are obviously two several different techniques for colouring bronzes. You can apply a patina over the natural chemical Bettina in the same method that they would have done in the foundry. This can be applied over a green stable patina. It will just change its colour. And it is, in my view, the least interventive of any of the process. There are of course other ways of producing Browns on bronzes, one of which is to use pigmented wax, which are the two images in the centre and the right hand side you have to remember that using wax is impregnated with pigments, is that, to all intents and purposes, you are applying a paint again. And we have, obviously, some disagreement about the use of paint on normal war memorials, but it is a method that you can use. One of the problems is that patina it or waxed bronzes that you're trying to replicate a varied coloured patina means that you're mixing little areas of different colours of waxes together. Which is fine for the first treatment, but as maintenance goes on, especially if you have to use hot wax again, then of course you're going to be stirring those mixed pigments together and you will end up with a bronze that looks exceedingly flat and uniform in colour. And the same would apply to the use, for those of you have come across it, bronzing powders. They are designed there again using metal based pigments to rub into the surface of a bronze, over which you then apply wax as a treatment. But they both are additional pigmented coatings, and I think, if it's possible to use traditional techniques in the way that the foundry would have done in the past, it's preferential. And this is an example of that chemical patination. 2b1af7f3a8
