Abstract

The working of bricks, in particular by grinding, takes place after the drying process and before the firing process, in which the bricks are heated as far as possible uniformly. The working thus takes place at a time when it is still possible with a low expenditure. A further advantage is the reduction in the mass which is to be subjected to the firing process.
