Applicant: Corning Incorporated
Inventors: Jingshi Wu

Publication number: US20220026148A1
Application number: 17/499,385

Abstract:
A method for heating ware in a kiln. The ware space of the kiln includes a plurality of temperature control zones oriented in a first direction, and a plurality of temperature control zones oriented in a second direction. The method includes heating the ware space in a first heating stage, a second heating stage, and a third heating stage. At least one of the following conditions is satisfied: (i) in one of the heating stages, a temperature control zone oriented in the first direction has a setpoint temperature that is different from a setpoint temperature of one other temperature control zone oriented in the first direction; and (ii) in one of the heating stages, one temperature control zone oriented in the second direction has a setpoint temperature that is different from a setpoint temperature of one other temperature control zone oriented in the second direction.
