Does anyone have a source or a recipe to make brass patina. Once upon a
time I had a bottle of it but was unable to get more when I was told by a
local retailer that it was no longer being made because it had arsenic in
it.

Most of my work is done with the copper foil method so if anyone can help
with a "home brew" -- I would really appreciate it.

Aw, geez...don't tell me the tree huggers are worried the stained glassers
are gonna poison some damn owl with a bottle of patina.

I had bought several bottles of the antique brass patina a while back at a
store closing. Now, I can't find them. I thought it was because my shop is
a mess....maybe the patina police confiscated them?

You can get patina for brass and copper through Dick Blick--I believe it's
by Designer's Options and there are two varieties, Patina Blue and Patina
Green. I also found them at Home Depot.

To make "home brew" requires certain chemicals that may not be easy to find
unless there is a school or shop around where you live. Also, many
home-made recipes require heat or other special circumstances which may not
work well for a mixed medium object. The pre-made ones mentioned above work
cold and can be brushed onto the piece--no immersion, no sawdust, no heat,
no torches, no special air extraction system required!

Of course, if you want a different color on your brass, that is another
issue. :)

Not a chance, but I may be wrong.

Jan, you want a patina, on lead/tin (solder) that looks like brass, right?

Try Weak copper patina and don't know what else. But its not arsenic,
generally when a major producer stops producing a product, it is because it
is not profitable, PERIOD.
It never would have hit the marketplace if it had arsenic in it.

Call Inland customer service, maybe they can help you with a place to start.

they did have to stop marketing antique brass patina because of the toxicity
of the ingredients (or so i heard). i create a similar look by using copper
first followed by diluted black. practice first. it rarely turns out the
same way so not great for multiple pieces that need to match. michele

What do you dilute the black patina with? Water, lacquer thinner, turps?

I don't know what is in the black patina, but the brass/copper ones I can
get at Home Depot are already very dilute. Liver of Sulfur (for turning
copper black) is diluted with water. Most of the recipes in my patina book
are created with distilled water and various salts and acids.
