Bullseye GlasTac is a liquid holding agent that keeps glass pieces in place while you build a fused design, then burns out cleanly during firing. It dries slowly and stays pliable, so you can reposition pieces as you work. A light organic colorant lets you see where it has been applied on clear glass and burns away in the kiln, leaving no residue on the finished piece. GlasTac is water soluble. Available in 4 oz and 32 oz applicator bottles.
