Oven used for annealing
A mechanized annealing oven that is at high heat at one end and air temp or nearly so at the other. A conveyer carries glass pieces the length over the time needed for annealing. Saves the energy of reheating and the wear and tear of a heat/cool cycle that an oven requires, but only cost effective in a heavy production shop. Sometimes lehr is used as just as a name for a cooling oven.
a type of large kiln which is used to allow the glass to cool gradually, removing stress points arising during the forming process of the glass (a process called annealing)
a teaching or sermon of Biblical doctrine
