>>Can anyone of the chemists out there tell me how to blacken brass to use
as a waterhouse stop on a Darlot lens?

Go to the Public Library and look for books on metal working, finishing,
etc. also look for a book called a Formulary. Several books go by that
title and contain scads of formulas for coloring metals. E-Mail me
privately and I will send you a list as an attachment.
