Annealing
The annealing of glass is the process by which it is heated to and held at a controlled temperature for a defined period to relieve internal stresses. Careful cooling under controlled conditions is essential to ensure, that no stresses are reintroduced by chilling or quenching.
Annealing Schedule
Thickness | Heating Rate | Time /min. | Temp. Δ X | Rate I °C/min. | Rate II°C/min. | Rate III°C/min. |
|---|---|---|---|---|---|---|
3,0 | 130 | 5 | 5 | 12,0 | 24,0 | 130 |
6,0 | 30 | 15 | 10 | 3,0 | 6,0 | 30 |
12,0 | 8 | 30 | 20 | 0,8 | 1,6 | 8 |
