I'm currently using pieces of tin can for

I've tried muriatic acid (which was effective in

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!

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.
