Abstract:
A method of coating a substrate in which preheating of the substrate is required, said method comprising the steps of:a) providing a device for heating said substrate, said device comprising at least one, heat-producing component and at least one glass-ceramic plate, herein said at least one glass-ceramic plate is provided with at least one recess and said substrate fits in said at least one recess so as to be on said at least one heat-producing component; b) placing said substrate in said at least one recess so that a surface of said substrate to be coated is arranged on said at least one heat-producing component; c) heating said substrate from below to a process temperature required for the coating with said at least one heat-producing component; and d) removing said substrate from the device for the heating and then placing said substrate in a coating chamber; and subsequently e) coating the substrate in the coating chamber.
