This fused glass manual describes methods to control and increase chemical/color reactions in Bullseye brand and similar glass. The broad color spectrum of reactive glass is identified and charted in degrees of reaction. Multi-layered treatments and experimentation are clearly defined with step by step instructions. The images are made within the studio processes, so are not expected to be 'high art', but rather a record of results that can be reproduced and amplified upon with your own experimentation.
