Glass Fusing Schedules
Glass fusing involves heating glass to temperatures where pieces bond together. The key to success is proper ramp rates (heating speed), appropriate top temperature, and correct annealing (controlled cooling). Thicker projects need slower schedules to prevent thermal stress.
Fusing Levels
- Tack Fuse (1350-1400°F): Pieces stick together but retain original texture and edges
- Contour Fuse (1400-1450°F): Edges soften and round, some detail remains
- Full Fuse (1450-1500°F): Glass melts together into a smooth, flat surface
- Slump (1200-1250°F): Flat glass bends into a mold shape (done after fusing)
