Summary for darkening brass with selenious acid Discussion
Darkening brass w/ selenious acid is the goal of a UK kitchen hardware manufacturer who is trying to locate a 1967 Metal Finishing paper by Janjua, Toguri, and W. Charles Cooper, believed to cover coloured films formed on copper by selenious acid. In response, Ted Mooney says Finishing Publications Ltd & Metal Finishing Information Services in Stevenage, Herts may have the article, though as an information service they would likely charge for access. He also notes that he had the old issue until recently and suggests writing Berl Stein of NiCoForm, who may be willing to photocopy and email the article. Mooney adds that the Metal Finishing Information Services CD-ROM did not show the exact reference, but did show a related entry, implying the citation may be hard to trace but not impossible to obtain through private archives or paid document services.
Q. I work for a kitchen hardware manufacturer in the UK, and I’m currently working on a process for darkening brass using selenious acid.
I’ve come across a reference to a paper published in ‘Metal Finishing’ in 1967 that seems to describe exactly what I’m trying to do. Unfortunately the journal is out of print; they only have online archives back to 1995, and the paper is not online anywhere else.
The reference for the paper is this: Janjua, Toguri, and W. Charles Cooper. “No Title” Metal Finishing. 65 (5): 54. 1967. I believe the title will be along the lines of ‘The formation of coloured films produced on copper by selenious acid’.
I was hoping that someone would have a suggestion for getting hold of the paper. Any help is much appreciated.
Thanks,
Will

A. Hi Will. “Finishing Publications Ltd & Metal Finishing Information Services” (not related to Metal Finishing magazine) in Stevenage, Herts probably have it, but they are an information service so they’ll probably be entitled to compensation. I had it until last month when I gave my old issues of Metal Finishing to Berl Stein of NiCoForm [a finishing.com supporting advertiser]; if you write him, I’m confident he’ll be happy to photocopy it and e-mail it to you.
But back to “Metal Finishing Information Services”, their CD-ROM does not show your reference in Metal Finishing magazine, but does show this one:
