Techniques to Rust/Patina Tin
 

I'm currently using pieces of tin can for
a project and am trying to create a rust patina
on the surfaces.
I've tried muriatic acid (which was effective in
stripping the shiny plating on the metal), followed by
a clorox/vinegar bath (which blackened the metal),
but have been unsuccessful in inducing a deep brown rusty
coating.
Any suggestions would be greatly appreciated!

You might try ferric chloride and/or ferric nitrate.

You are washing the metal with another acid instead of neutralizing it
with a basic solution. Try soda [sodium bicarbonate], soda ash [sodium
carbonate] or lye, [sodium hudroxide],rinse with clean water. then
leave it in a moist area for a few days. You should get a great rust
bloom.

Spray on wood stains and clear-coat.

Salt is the traditional method. Paint it with a heavy brine, seal it
in a plastic bag in a warm place for several days and then buff it to
a shiny brown.

I'm sure there are more specialized solutions, but this method has
worked for me in the past.

What about spraying it with a salt solution? Not sure what effect
that'll have...

Works very well, if you enclose the object in a plastic bag for a
couple of days afterwards and let it sit someplace warm.

Just don't leave it in too long or it will pit.

When you take it out of the bag and buff it until it's a shiny brown
you get a nice even brown.

I used to do that all the time. There may be better ways, however.

Best to strip off the tinplate first. Tin oxide is transparent.

But if it's any suggestion, the coffee can I keep my rock
salt for the sidewalk has a lovely brown, er, patina.

It could be art. Anyone want to buy some art?
