Andrew Groner creates wonderfully mystical creations in various shapes, sometimes marbles, sometimes cold worked cubes and other shapes. He uses mostly gold and silver fuming to achieve his glass magic with a range of earthy colors. He often features large air traps in the middle of his marbles, like this one here, which take on planetary and other shapes. This one appears to have a planet inside of it which is expanding and contracting and forming all manner of cosmic material as a result. So fun! Signed 'AJG 07'.
