One of the questions I get most often is “How do you color the volcanic rock?”

In my painting process, each individual grain of rock is pigmented (colored) before it goes onto the canvas.   I use larger grains and very fine grains and grain sizes in between.  In all cases, each grain has its own coloration before it gets used.

I’ve been using Earth as a painting medium for a really long time.  Over the years, I’ve innovated and come up with new ways of working with it.  At one point, I decided to explore this idea of coloration of the rock a priori.  It took a while, and wasted a lot of chemicals and materials in the course of it.  But eventually I had it sorted.

New twists reveal themselves all the time.  But here’s a peak into what it looks like.

 

 

I hope you like it.  Send me a note if you’d like to talk about anything.

Cheers!
