Art supplies I use are anything I can get my hands on. I have used metal shavings and metal dust from the floor of hardware stores by the key grinder. I also scored on a very fine gold powder that i blow onto a surface that has been recently varnished so it sticks as well as not losing the reflective property of the gold. View an example here.

I experiment with many different materials. Many years ago I was given the art supplies of an artist who's name was Ann Daniels. It was a huge range of supplies that included brushes, oil paint and a lot of items I still don't know what they are for. A great example of these items would be the encaustic painting materials that I've had for years and never knew what the powdered paint was for. Take a look at the encaustic application I used on this sculpture.

I'm always experimenting with different sorts of materials and read a lot online about processes other people use. I learned a lot about processes when I was in college at The School of the Art Institute of Chicago. I enjoyed watching demonstrations and enjoyed some of the failures I experienced as well.
