Copper electroforming question – newbie

Posted by admin on June 21st, 2009 at 03:29am

I have successfully electroformed a leaf after sealing it and covering with conductive paint. As soon as I remove it from the bath, it is a bright salmon colour but changes extremely rapidly (seconds to minutes) to various blotchy tarnished shades.

As soon as I remove it from the bath I rinse it thoroughly under running water and before it dries it begins changing colour. It does not even give me enough time to dip it in a sealant.

How do I stop it from changing colour?

Thanks in advance for your help!
