ABSTRACT:
This specification is directed to a UV-base ceramic paint composition and a method of forming a glass sheet with a UV-base ceramic paint thereon. The method has the following steps. A UV-base ceramic paint is applied to the glass sheet. The UV-base ceramic paint includes selected ceramic paint components along with, as a new component thereof, finely divided zinc metal powder. The glass sheet is subjected to UV radiation and then heated to a temperature which softens the glass sheet sufficiently so that the glass sheet can be formed. The glass sheet and the ceramic paint thereon are engaged with a fiberglass covered forming die to form the heated glass sheet to a desired shape. The forming die is removed from engagement with the glass sheet. The finely divided zinc metal powder addition to the ceramic paint is credited with being effective to prevent sticking of any of the ceramic paint to the forming die. The glass sheet is cooled to obtain a formed glass sheet with a ceramic paint thereon.
