Disclaimer:I have no commercial or other financial interests with any of
the products, services or suppliers mentioned in this article.
All products that I have been able to locate and validate have
been included; however, there may be others available. I would
be grateful for any further information about any new or
alternate products, as well as corrections or clarifications to
any of the information provided. This is a work in progress.
An Introduction:
There is a wealth of information about this subject to be found
on the internet; however, to the novice much of it is
confusing. Considerable discussion has been transacted in the
various ship modelling forums, and some very useful information
can be obtained from the manufacture’s product fact sheets.
The following is a collection of thoughts and ideas resulting
from some basic research I have conducted in trying to find
brass blackening products here in Australia. I hope it is of
some value to fellow modelling shipwrights.
I have drawn on the information provided in many of the above
sources in writing this article. I cannot take credit for all
of the information provided, and wish to acknowledge the various
authors of the discussion forums from which I have drawn some of
this information.
A word of
Warning!
Consistently and emphatically, the product
makers and suppliers, as well as the various
sources of information, stressed the same words
of warning and caution.
“The
chemical ingredients used in these products are
dangerous.”
Even though they are safer than most industrial
agents, these products and chemicals must be used
with caution! Wear rubber gloves, a face shield,
and a mask. Open the window and put on the fan.
Follow the manufacturer’s instructions to the
letter. Make sure you keep these agents in a well
secured, safe lockable cabinet; and keep away from
kids and pets. In other words, use your common
sense!
Now that you maybe rethinking the use of
these products and processes, and I have covered my ‘you
know what’ – please acknowledge that you are aware of
these hazards by pressing the accept button to access
the article. If you do not feel competent to undertake
chemical blackening, press the decline button.
