A disk of Pt or Pt alloy is sandwiched between the divided cylindrical parts of a stirring rod for glass melting, a plunger for glass extrusion, etc., and is integrated with the cylindrical part. Since the Pt or Pt alloy coating on the outer circumferential surface of the columnar part is welded to the disc and is integrally reinforced,
As the stirring rod rotates and moves up and down in the molten glass, and the plunger moves up and down in the molten glass, resistance is created between the Pt or Pt alloy coating and the molten glass, and the coating is separated from the cylindrical part. Even if such a force is generated, the coating will not be twisted and damaged, nor will it be stretched or deformed. Therefore, there is no need to increase the film thickness to maintain the strength of the film as in the past, but rather the film can be made thinner because the film is reinforced, and the durability of the stirring rod and plunger is improved, resulting in a longer service life. increases.
