I first drew in the lines of the shell and it's chambers, then drew over them again with a clear dimensional glue. I painted the image, then shaded it with micaceous iron oxid (that is some cool stuff!) and them added the iridescence using a large flaky opal glitter. For a pleasant change, I got exactly the effect I was after - now that's a great feeling.
When everything was dry, I applied some heat activated foil in a copper color to the raised outline. I managed to burn my fingers in the process, but it was fun anyway. That stuff could prove addictive. Oh dear...
I wish now that I had used copper rather than gold inside the chamber sections, but I have some more of these little canvases to play with. I think I just might make a series of them in different colors.
