I made some salt water and let it dry.

Thanks Alex. Actually I had tested it over night on the same penny and washed off the crust it looked as good as new underneath.

I'm glad to hear it. Ahhh lovely copper... birth of the metalurgy for humans I think. Persians? I don't know.. but copper age is right after stone age.

Thanks John, I had to give you credit too. What kind of salt did you use? Your crystals are alot bigger than what I got.

I used Morton non-iodized coarse sea salt, crushed to a fine powder, boiled in microwave, I kept adding salt until the water was completely saturated, until the crystals were still visible at the bottom of the shot glass after a quick boil.

Yep , I made some salt water with table salt and added it to the penny and let it dry.

I have run my course through all my movie theme songs. One of these days I will buy Cinescore, maybe.

Thanks Rick, It was about 3 and half hours.

Thanks Hoop, That really is a possibility.

Thanks

John had a cool idea. I want to see if I can get bigger salt crystals.
