It's roughly 8"x12", made of vitreous enamel on etched copper. This took me about eight months to finish, although I could have finished it a lot sooner if I hadn't been working on two dozen projects at once.
Arms are for pussies.
To explain the process, I first need to explain the terms because most people have very little understanding of enameling unless they've taken a class in it.
Enamel is a mixture of ground glass and other things designed to fuse to a substrate, usually copper, gold, or silver, calculated so that the glass melts and cools at the same temperature as its base metal. It comes in transparent and opaque colors, and can be seen on a wide array of items- particularly jewelry, small sculptures and kitchen wares. It's an ancient art form practiced in various cultures all over the world.
First I used acid to create a relief, using a resist made from a combination of painted asphaltum and a copy of a sketch printed in toner on special heat resistant PNP transfer paper burnished on to the copper with a hot plate to make it melt. Here's a picture of it from before I put the enamel on it: http://www.newgrounds.com /dump/item/ec3f5b4016f3ef a999c770412e6f4e46
The background I made using a process I made up as I was going along, dropping droplets of an asphaltum, water, and maybe oil (it was at least six months ago, I don't remember exactly) while the copper was sitting on top of a hot kiln, and the designs were left in asphaltum as the water boiled off. Then I stuck it in the ferro chloride, cleaned it off, formed it (mostly with a plastic hammer to the back) and started applying transparent enamels to it and firing them.
Photographing it without a ton of glare has been a pain. It looks better with more light on it, and in person when you can really see the layers of transparency, but this is the best I've managed thus far.
