I do fire painted copper using an acetylene torch. My problem is finding to coat the finished product in order to protect it. I have tried urethane (both spar and poly), lacquer, varnish, protecta clear, auto clear coat, ren wax, spray finishes to protect paintings and photo and documents(6), hair spray. spray car wax and maybe a couple of others. The main problem is it kills alot of the color especially the reddish blue and deep blue colors. Any help is greatly appreciated

Sorry but anything you put on it will change the color. It's all in the way light is absorbed or reflected. That's the way it's been explained to me.

Like Tony said, anything will have an effect on it, the people that did the DVD on flame painting copper said the use lacquer with all its humidity problems etc. There are a number of threads in the patina forums dealing with the coloring of copper by heat. Placed into direct sunlight the colors will fade in time.Posted Image

FWIW, here's a link to one of the threads on interference colors.

We all love the interference colors. So the trick is preserving as much of them as we can. Because it's about the refraction of light....thinner will alter the refraction the least. Like you, I've tried about every kind of clear out there. Protect a Clear has given me the thinnest coating, it's self leveling "feature", and viscosity seem to be the reason.
If you find anything NEW :),please let us know.

I have found a product from Krylon which they call their low odor material. The can says it is an acrylic spray. If the copper gets a very light misting from a distance it seems to hold most of the color.
