My glass fusing work is done mainly using Bullseye Glass which is all tested for compatibility. One cannot mix glasses of different co-efficiencies or they will crack. Unlike glass blowing, my work is all done when the glass is cold. Pieces are designed, cut and laid up cold, then fired to create one solid piece of glass. The process may involve texturing during a firing, shaping, molding or casting. All this is done in the kiln. One finished piece of work may go through many firings until the completed shape evolves.
Because of the cost of fusible coloured glass, I have been experimenting with recycled glass. It gives me the chance to save some glass from the landfill and turn it into something beautiful and often...functional as well.
