What temperature should I use for tack-fusing?
A tack-fuse is a "lighter" fuse than a full fuse. Tack-fusing is a kilnforming technique used when you want to join two or more separate pieces of glass together, but also retain their individual characteristics.
Tack-fusing temperatures are lower than full fusing temperatures, but there are still many variables to consider and there isn't one "tack-fusing temperature" that can be used in all cases. By reading Technote 4: Heat & Glass, you can learn basic principles for tack-fusing glass.
