Copper electroforming question

Hi everyone,

It's been a few years since I've been on Wet Canvas, I used to do glasswork.
I just started copper electroforming and have a question, I'm not sure if I'm in the correct place, if not please let me know where to post my question.

I'm concerned about how to dispose of the waste water that I used to rinse off the anode. It is contaminated with a large amount of copper and it doesn't seem like a good idea to just dump it out in the yard or rinse it down the drain.
I did a little research and found that the waste from this hobby can be very bad for the environment.

So I'd like to know how everyone who does this type of work is dealing with it. I've stopped electroforming until I can find a solution.

Thanks so much for any help!
Donna

Presumably you are working on jewellery?

Disposal is a rather specialist topic and I wouldn't know where to start.

Hi Doug, yes, jewelry. I'm hoping others may jump in and share how they handle disposal of the waste.

I just did a quick Google Advanced Search of wetcanvas and found this thread on disposing of paint water which can contain toxic metals such as cadmium and cobalt. Hope it helps.

Thanks for your help, the article doesn't really apply to copper but it's interesting reading.

Re: Copper electroforming question

Hey, Donna. I've never done electroforming, but I do deal with silver/bronze pickle, which does contain quite a large amounts of copper and would never dump it in a drain or backyard. If the amount of waste water is small, I throw some steel wool into the mix (do this outside, the smell is absolutely horrible). The wool can be gathered and recycled. by doing this, you can get rid of most of the copper. The remaining water is neutralized with baking soda. If you do have a lot of the waste water, then I'd store it in a plastic canister and find someone locally who can dispose the waste for you.

Re: Copper electroforming question

Hi Teea, thanks for responding! And thanks for the info about the steel wool, I read about that somewhere else also. I'll try it, I think for the small amount of rinse water I'll be creating that soaking up the copper in the water with the steel wool and neutralizing any remaining electroforming solution that may be in the water with baking soda will do the trick. Thanks again!
