Annealing Temperature & ScheduleFurnace Guild
Calculate strain point, anneal point, and soak times based on glass type and thickness to prevent thermal shock.
Always calculate based on the thickest wall or solid base of the piece.
Target Annealing Cooling Schedule
Soak for 101 minutes (1.7 hours) at 515°C to equalize temperature.
Cool slowly from 515°C to 460°C at 36°C/hour (approx. 1.5 hrs).
Cool down to room temperature at 192°C/hour.
