Thought I might ask the pros here. I found it difficult to buy tin plated copper and so I took a copper sheet, put it in distilled water with a bar of tin / lead and ran current through it. (anode was in tin / lead bar) The results were amazingly good. Looked like a professional job and I only used a bucket. I needed to add a handful of table salt to the bucket to get the water to conduct well. My first question is, someone said I might release chlorine gas, but I used distilled water and so I don't think it is true, at least I am not dead yet. Second is, It appears to release huge amounts of Hydrogen with the salt in the water making it more conductive. Useful amounts? Any ideas? Third question is, what the heck is that white stuff at the bottom of the bucket?
