DEFINITION

Classification: 156/89.11

With vitrification or firing ceramic material:

(under subclass 60) Processes which include the step or heating a ceramic material of which the lamina and/or coating is composed to a temperature sufficient to vitrify or fire the material.

(1) Note. The firing may be of a decorative vitreous layer subsequent to its application to another lamina in a direct transfer operation to remove the backing sheet, usually by burning
