From hot to cold – Annealing process. Annealing describes the process in which the glass containers are cooled down after the moulding process. This is achieved in a heated furnace called "Lehr", where the glass is slowly cooled down to avoid breakage or damages. The temperatures of this cooling area are between 590 °C and 450 °C.
