I bought some Liver of Sulphur last night. I mixed it as per the
instructions on the can and waited for the brass to tarnish. A couple of
hours later nothing, so I left it overnight. This morning it still had not
changed. Has anyone worked with this stuff? What concentration is required,
or is there a special preparation required before it's immersed?
