My directions for rusting tin say:
Pour APPLE CIDER (Must be APPLE CIDER) vinegar into an all-metal cookie
sheet with sides. DO NOT use Teflon coated, enamelware, glass or plastic
Immerse tin into APPLR CIDER vinegar making sure the piece of tin is
completely covered. Leave the tin in the vinegar for approximately
20 to 30 min. IT WILL NOT RUST IN THE PAN OF VINEGAR. Lift tin out of the
vinegar and stand up on edge to dry. (Be sure to protect drying surface).
DO NOT WIPE VINEGAR OFF. The tin will rust as it is air drying. The rusting
could take 30 min to 3-4 hours. depending on the humidity in your area.
The longer you air dry, the more rusty it looks. When tin is completely dry,
it will turn a copper color with uneven streaks and swirls. These directions
are for light rusting.
For Heavy Rusting:
Must be done in a well ventilated area or outdoors. Use all metal cookie
sheet with sides. DO NOT use teflon coated, enamelware, glass or plastic
containers. Measure 2 cups of CLOROX or any household bleach and pour into
metal cookie sheet with sides.
Add 1 cup of APPLE CIDER vinegar and mix thoroughly.
Immerse tin into solution. Tin has to be completely covered.
It will start rusting immediately in the solution.
It takes approx. 2-3 min. Lift out of solution and stand on edge to dry.
It will become very rusty. Let air dry completely for approx. 1-3 hours
or overnight. When it is completely dry, wipe some of the rust off
with a dry cloth...this is optional.
