I tried one of the recipes I've looked up for making stuff rust quickly. The one I used was salt and vinegar. I bought some silver colored safety pins and small bells and put them in a glass and covered it with vinegar and put about a tablespoon of salt with it. I left that overnight,and the next morning I took them out and laid them on paper towels. Since it was so hot outside and this stuff STINKS...I set it on the porch. Right away it started turning black, and within a couple hours it actually had rust on it. BUT.....that's as far as it got. Then I took some and spray painted them with red oxide and sprinkled with cinnamon. I like it better, lol!
The one on the left is red oxide primer and cinnamon; the one on the right is salt and vinegar.
I took about 30 photos of this......it's so hard! I gave up and chose the clearest.......and maybe tomorrow I'll try again!
