Thanks ana! I didn't use chemicals from a craft store though so I don't know if you can achieve the same type of patina with that. I raided the chemical cabinet at my lab to see what would work based on the patina recipes I found on a metal art website. WARNING: Please do not play with chemicals if you don't know what you're doing. With that said, my final solution ended up being a hot immersion (90 deg C) of ferric chloride, sodium nitrate, ferric ammonium sulfate, sodium thiosulfate, and deionized water.
Very cool!!!!
