Patina, pickle and production


©2020 Barry Smith - Patinated 19cm long copper leaves
I'm making a stash of patinated copper leaves for the DEP galley-shop.  It has been quite some time since I have made copper fold formed leaves. I'm making some that measure about 12-13cm in length; and another batch about 19cm in length.

Warning process photos follow.

I will give the leaves a coat of matt varnish to fix the patina; the leaves will then need a grinfg to get rid of sharp edges and create a few bits of raw copper highlights - maybe I will get to that over the weekend.

  1. These are beautiful! half a lifetime ago I used Porzelack '0' diamond hard solid wax to hold the patina on copper, it buffs well but darkens the patina
