Dichroic glass adds dimension, pattern and surface variety to your fuse glass project. This 90 COE fusing glass is designed for use in the Fuseworks™ Kiln. TO USE: Place glass face down on a flat cutting surface. Score glass using a glass cutter to desired shape and break. Layer glass on kiln paper inside kiln and fuse. When using clear dichroic, place it face down on top of the base glass. When using black solid or pattern dichroic, place a piece of clear glass slightly larger then the base glass on top to protect the pattern/color.
