Heat Colouring Copper Experiments

After last week’s workshop with patinas I decided to experiment a little more with the Jel Flux technique, it is so much fun to do and I love the results!

Heat patina on copper

First I used it on a piece that had been sitting on my bench for a while. This was the blown up version of one of my little squares, design drawings I like to do at times to take a ‘snapshot’ of where I am at the time.

The trick is in the torch firing, you need to get the copper red hot, then wait a little bit before quenching in water. As soon as you take it out of the water the colour is there! Magic!

Applying the heat can also be done in a toaster oven, set to 180 C ( 350 F) the piece on the left was cooked for 30 minutes. You’ll need to time this visually as the weight and size of the copper will play a part in the time required.

This is a very strong colour for copper, no sealing wax required and the red stays vibrant for years. The oven baked copper stays shiny, while the torch and subsequent quenching gives a nice matte finish that would contrast nicely with shiny silver elements. Polishing the torch fired piece works well too, the colour is in the metal and doesn’t polish off.

I really did go nuts for a day or so, I’ll post more to my Facebook page: GC Jewellery Studio in the next few days, come and have a look and Like the page while you’re at it:)  I hope you’ll try this technique, I’m sure you’ll love the variety in colours you can get, especially with the oven bake method, enjoy!
