Patty Grays technique to combine color and hue through layers of glass is “leading edge” in the kiln formed glass community. She is a pioneer of innovation and technique. I thoroughly enjoyed attending one of her classes this summer and this is one of the pieces I created after the class. This is an 8″ disk that is about 3/8 ” thick. It started with 1″ squares of alternating clear and orange. (I thought it was red!). Those squares were covered with alternating 1/2″ x 2″ rectangles of clear, blue and green transparent glass. The result – a happy accident!
