When your piece is finished etching, here's what we do! (this was about 30 mins - may take longer just try scrap pieces until you get your timing down ;) ) IMPORTANT!!!! To dispose of etchant (if it gets contaminated or is taking much longer than usual to etch.. takes a while trust me!) Neutralize your acid SLOWLY with baking soda and seal in a mason jar. Take it to your local landfill and ask them to dispose of it as HazMat!!!!
