Meet the new go-to holding agent: GlasTac Gel. It is thicker than regular GlasTac and has a “tackier" feel but still burns out cleanly. Glastac Gel holds its applied shape well, although you can also apply it with a paintbrush, making calligraphic powder lines easy. The gel stays sticky longer, allowing for more working time before it dries. It's strong holding power allows you to move your tacked sheets into the kiln sooner.
