Firecolour - A new art medium

Heather's portrait - heat , patinas on copper sheet

Process:
1. Anneal to dark gray / black
2. Erase back to copper with torch and etching.
3. 'Bloom' exposed areas with torch to desired colour
4. Refine blacks with chemical patinas & water resists.

Qualities of preservation :

No finish necessary . Chemical layers interfere with the refraction (colours) . I have some sealed plexiglass frames to completely isolate the copper from oxygen , but haven't found them necessary after 6 years of careless storage , still vibrant as ever !.

Hi Colina, and welcome to

Hi Colina,
and welcome to the Artmetal family. Your heat painting is amazing indeed. The details, tones, designs, show a depurated technique. The furthest I`ve got with some copper heat tinting, turned dull in a few weeks. I do a bit of Cu sculpture and would like to give it some tint highlights. As I`ve checked the internet to find out what to apply to preserve beautiful rainbow tones, nothing is really said. Another thing that surprises me a lot, is your generosity openly showing how people could apply techniques that might have taken you so long to discover and learn well. I`m sure your kindness will be well retributed wherever you stand. Nelson.

Hi Nelson , name's Colin ,

Hi Nelson ,
name's Colin , and thank you , It's nice to be among artists of such high caliber here. Re ; heat tinting , the flatness of the sheet is essential for lasting and varied ' rainbow colours ' , just as the flatness of puddle water with oil on it will produce beautiful light refractions .
As I was saying in the above comment , exposure to oxygen is the key factor , "greening" copper is a very slow process even in outdoor conditions as you probably know . Anneal and "fire paint " your sheet , keep it indoors and it will preserve as long as any comparable medium under similar circumstances .
As far as sharing the techniques I don't mind because A) There is so little real interest in what I do that it's not a danger ;) B) I challenge people to take it further than me! Show me something new I can add to my repertoire . C) that's what I figured this site was about , exchange .
I appreciate your sound questions and hope I answered them clearly , thank you ,
Colin

Write a book..

.. it's astounding. Your stuff makes mine look kind of ham-fisted. I had came to similar conclusions about about the technique and found sharing it very rewarding. If you have minute, check this out.

This is absolutely amazing!

This is absolutely amazing! I don't know alot about art and I don't experiment with alot of new mediums, but I really want to try this! The only problem is that I don't know what any of the terms, that you use, mean. Could you please explain them to me?
