Plique a Jour in and on Copper

Several years ago I read an article by Bill Helwig on Plique a Jour using copper sheet and a backing of copper foil. Not until recently did I find the time to experiment with the art of plique a jour and remember this article to review as I began my exploration. I could remember him saying enamels do not adhere to copper.

There is still some part of that statement I have questions on and will get to those later. But for now wanted to share the process. You can read the whole article in Glass on Metal   www.glass-on-metal.com/pastart/bridging_the_gap.htm but to wet your appetite here are several photos of his technique.

One of the wonderful properties of copper and enamels is the warm qualities it give the enamel! In image one he has cut out the copper sheet and in image two he has secured the copper foil to the back of his design. From here he has filled the cells and fired to the point of completion and of course there is fire scale to deal with but he has created a beautiful piece!

    Thanks for the links, hints and great advice. The tutorial with copper foil as a backing worked well with a copper piece as long as I was diligent in cleaning up the cutouts and used the same care with firescale cleanup between torch firings.

    I tried the copper foil with .999 silver piece and managed to get it so hot that the foil fused with (alloyed with?) the silver…I broke the glass attempting (unsuccessfully) to get the foil off. I will try the titanium backing with the silver next – and maybe attempt to exercise a little more torch temp control at the same time.

      Sounds interesting. I use a kiln to have more temp. control. Just bring the torch up very slowly and you will see the enamel melt.

      Good luck. Patsy

    Thank you for the sensible critique. Me and my neighbor were just preparing to do some research on this. We got a grab a book from our local library but I think I learned more from this post. I’m very glad to see such fantastic information being shared freely out there.
