When creating glass artwork with recycled glass, color play often isn’t an option. By stacking and tack fusing, you can create visual interest. Using ‘white space’ in conjunction to ‘stack and tack’ gives you a huge variety of options.
For example:
This piece is a large circular vessel. After cutting the circle, a 1″ wide strip was removed from the inside (drawing a square within the circle). Then squares of the same sheet of float glass were stacked over the gap and tack fused.
