This abstract has a geological feel to it, as many of my abstracts do. I used acrylic modeling paste to build up the copper colored elements and create additional surface texture on the canvas.
The first photo shows the canvas with the modeling compound applied. I like to add color to the modeling compound so I can see it better against the white canvas. There is also a small concept sketch where I was working out the composition. It's surprising to me how much the finished painting looks like the sketch.
The copper areas have metal leaf applied. The copper leaf was then carefully treated with copper sulfate solution to create an authentic black patina on the metal. The rest of the painting was done with artist quality acrylic paint (Golden brand) on gallery wrap canvas.
