During my December stay in north Rochester, I took an evening stroll down the Seth Green trail, into the Genesee Gorge. While gazing at the massive icicles that had formed along the shale and limestone exposures, I noticed a layer of rock -- about a foot thick -- cutting a reddish line across the otherwise gray cliffs.
I climbed up a short, snowy slope and grabbed a small chunk. I was intrigued by the possibility of painting with Rochester's only mineral pigment. A week or so later I used a hammer to break up the small rock and then grind it into a powder. I mixed some with water and made a few quick, improvised watercolor sketches.
I mixed the rest with acrylic medium to make a sort of gesso ground for a few panels. Lacking proper grinding equipment, I was left with a very gritty gesso -- rather like sandpaper when it dried. But, still, I like the thought of painting some future Rochester scenes on Rochester rock. Rock-art for the ROC-ART project.
