ABSTRACT:
The method for sealing a glass stem wafer into the neck of a CRT has a plurality of burner tips disposed completely around the neck. The burner tips are angled such as to create rotating hot gases around the neck. This eliminates the need to rotate the CRT bulb, the wafer or the burner tips, to achieve a uniform seal.
