    Sorry I'm not really sure Sheena I don't use much copper. Here is a sheet on metal finishes, many of them non toxic which might suit you https://dspace.library.colostate.edu...pdf?sequence=1 I also bought a really I. Depth book a while back but it turned out to be mainly for copper so it's still in the wrapper. A lot of chemicals going on to get some great effects though, I particularly liked playing about with rice and vinegar on my fold form plaques!

    It's good for a play about, this was a panel I did with rice and vinegar in a sealed container for weeks. Just a bit of fun

    Nice! It looks crumpled silk catching the light and I always love the verdigris colour.

    Yes it works on copper and brass, although the problem with silver solder remains, as mentioned above.
    But the best multicoloured patina of all for coper once done over with the soapy brass brush is to selectively flame it with a mini-torch. Sorry if youve already seen this. Dennis.

    Sorry, I dn't see Caroline's, the verdigris is beautiful too and lasts well, if waxed.

    The torched colours seem to last for years Sarah. There is a test leaf in the bottom of my work box that is as new after three.
    The enigma is that the colours disappear when waxed. Why is that? Dennis.

    Ha ha, that explains it better. Nancy Hamilton is a force of nature, but I wouldn't have her living in. Dennis.

    Thanks Dennis the waxing enhances it well and my customer liked the fact that it would continue to evolve in colour even behind glass.
    You are right about waxing the torch fired colour, its strange because it would be good to enhance it even further as I found that it's a good colour but really dull
