Gold Leaf

So, after a hiatus, during which I’ve been crazy busy with author events and workshops, I’m back for the last lap on the painting. In fact, I ran our of resin and had to wait until the hardware store could order the industrial quantity that I needed.

In that time I worked on the lungs and heart, adding gold leaf and bits of detail here and there.




The lungs needed a more organic feel, and I also added some golden veins to the heart.

With all the glare it’s hard to really get the gist of it, but there are several layers going on, and some pretty wild reflections. As my good friend Benjamin once said: “Some things are just better in person. Like side-boob.” And yeah, just like side-boob, for this painting you definitely need a good vantage point. The effect does change depending how close you get and from which angle you view it from.

The Copper Patina Experiment

It's been about 24 hours since I sprayed the disgusting and incredibly noxious vinegar-ammonia solution onto the copper to test. And It looks like the medieval formula beats out modern chemistry. The Muriatic Acid, a pool cleaning chemical you can buy at any hardware store, has actually dissolved the top layer of copper before it started oxidizing, leaving it much cleaner looking at first, then kind of discoloured and blackish. That black patina is actually a different kind of rust happening on the copper—one that I want to avoid. The black oxide is what happens on pennies when you touch one with your grubby ball-scratching fingers.



What I want is the verdigris, the green tint. Although I now know it is possible, I have decided to avoid using a weathered copper for this painting in particular. I want the heart as shiny as possible. Next time I will try a nail polish resist with the patina I made. You could do some interesting stuff!

I poured the 2nd layer and now I'm waiting for it to cure.

The Circulatory System

So the image I want to work with is the circulatory system. I love the idea of the heart as a pump. Haloed around the pump are the lungs.

Here you can see the connections from the veins and arteries to capillaries. In my mind I see a wing. I'm really not sure why, but I'm a sucker for bending metals. These are mostly copper plate and guitar strings.

Detail of capillaries

I get a feeling this is going to be a heavy painting. with a bit more relief than any of the other resin cast paintings I've done in the past.




Here it is, sitting on the table waiting for its next coating. I always want to do it so soon, but this time I have to wait until my copper patina experiment has worked out.

The Patina

I am experimenting with different acids and oxidizing agents to see if I can give this copper plate a greenish-blue patina. Basically I'm trying to force the process of weathering which turns copper that nice Statue-of-Liberty colour into an overnight event. The right side is muriatic acid, into which the piece was dipped. It looks cleaner than the original, but maybe it takes some time.

The rest of the plate is a sprayed on agent I made from vinegar, salt and ammonia. (This is basically a medieval recipe for making malachite, a blueish tone) The mixture smells terrible, and literally put me out of the house for a few minutes as it vented, but it is looking better than the straight up acid. I'll check tomorrow and see if it is feasible or appropriate to weather the copper a bit.

The Curing Process

I separate the layers by pouring epoxy resin on top. It's a finicky process that needs to be done in a sealed room. Over the next 14 hours the hardener catalyses, giving off a bit of heat in the corner of the studio.






So now, while I'm waiting, I'm trying to catch wasps. It's the yellow jackets I'm interested in. If I can catch enough of them, I will definitely use them in the painting. I need at least 3 yellow ones. I have two so far, but I had to left one go since it was brown, not yellow. :(

Wish me luck!

The Fused Glass Experiment

At the end of the night, this is the first layer. I arranged some fused glass pieces as the first part of the composition.

Here are some close-ups of the glass. It's very smooth and flowy, which contrasts nicely with the rough epidermis I've been working on.

 You can see that I've added some gold washes as well, and the blue-black shard is impressive. It's all about shine over here in Graeme's world these days.

The right side negative space

The background almost looks like a map. I would love to do another one of these as a straight up fantasy map. So I will cast the first layer of resin tonight, which should bind everything together. It takes a long time to cure and needs a sealed room to work well.
 

My tool kit includes the beer!

The Copper Landscapes of Mars

So I've started staining the background with copper. There are some very nice unexpectant results. Yes, none of the results are having babies, much to the chagrin of their parents, yet they are results welcomed into the arms of their relieved boyfriends.

Following are some details of the coppery textures:

The background is almost done. The next step is to set upon my milk-crate of materials, which, as I mentioned, contains a magical bag filled with many spools of broken guitar strings. Perhaps a metaphor secreted away for many years. Perhaps not.

Magic beans!
