Even red patina on copper

Hi Everyone!

This is my fist time posting a question although I have been lurking
for a few months and have found the site a wealth of and
that is why I am writing to you about my problem: getting a EVEN red
patina on copper. I have read Jinks McGraths very helpful book on
patinas and wrote to her on how to get a red patina on copper like
the one she has pictured on page 54. It is beautiful. I followed the
instructions but still have a problem. The patina looks spotty. I
have sprayed the flux on and then tried brushing it on. Brushing did
improve the amout of area covered by the patina but not good enough
for my liking. Am I expecting too much? Ms. McGrath’s picture has an
even patina. Is there anything I can do to get the flux to evenly
spread on the copper? Thanks so much.

I just picked up “Japanese Patinas” by Eitoku Sugimori, it mentions
using grated daikon radish to get an even patina.

Haven’t used this vegetable myself yet, but will give it a try at
some stage.

It sounds as though it might need a more thorough cleaning. There
may be trace amounts of oils from your finger prints on the metal,
which will inhibit the adhesion of the patina chemicals.
