SPRAY PROCESS FOR CREATING ELECTRICAL CIRCUITS

Kaolin is capable of withstanding temperatures of well over 3,200° F. without disintegrating. If water is applied to the kaolin, it becomes pliable to permit it to conform to curved supports if necessary. Depending upon the production circumstances, the template can either be expendable or it can be processed to be reusable indefinitely.
