I've made a copper piece (soldered and scratch effect on top) which at first looked amazing, but the patina set in soon after.
I have cleaned this using a lemon / salt solution and a course brush then applied Rennaissance Wax (sadly not worked with copper before so only just discovered this).

It still looked slightly dull but lighter but 3 days later, it is turning green round the edges and copper discolouration are now appearing.

Id hate to scrap this piece but I am unsure if I have done something wrong or not coated straight away.

Any advice please x
