GlasTac Liquid & Gel keeps your glass pieces in place before firing and burns out cleanly in the kiln. The liquid version offers slow drying for easy repositioning, while the gel is thicker, tackier, and great for strong holds, fine powder lines, or children’s projects. Both come in a convenient 4 fl oz bottle and make glass assembly simpler and more reliable.
When you’re layering or arranging glass before firing, you need a reliable way to keep every piece right where you want it. GlasTac is specially formulated to lightly tack glass pieces in place while giving you the flexibility to make adjustments as you work. Both the liquid and gel formulas burn away cleanly in the kiln, leaving only your finished design behind.
-
GlasTac Liquid: A classic go-to adhesive for glass fusing. Its slow drying time makes repositioning easy, and the organic tint helps you see where you’ve applied it on clear glass. Perfect for everyday use when you want control without rushing.
-
GlasTac Gel: A thicker, “tackier” version that stays sticky longer and holds stronger. Its body makes it easy to apply with precision (even with a paintbrush!) and it’s excellent for sheet-to-sheet tacking, children’s projects, and creating fine lines with powders.
