Abstract
A molten glass sampling device and method of operating the molten glass sampling device are disclosed. The molten glass sampling device includes a sampling cup and a rod. The sampling cup defines an interior cavity and is coupled to the rod, which is composed of an electrically resistive material that maintains an electrical gradient of at least 50 kV per foot for at least one minute. The molten glass sampling device can tolerate the elevated temperatures of molten glass and can handle energized molten glass. The molten glass sampling device may additionally include the added functionality of the sampling cup being movable relative to the rod.
Claims16
A molten glass sampling device comprising:
- a sampling cup having a first end and an opposed second end and defining an interior cavity, the first end of the sampling cup defining an opening to the interior cavity and the second end of the sampling cup being closed;
- and
- a rod coupled to the sampling cup, the rod being composed of an electrically resistive material that maintains an electrical gradient of at least 50 kV per foot for at least one minute.
A method of operating a molten glass sampling device, the method comprising:
- providing the molten glass sampling device that includes a sampling cup and a rod coupled to the sampling cup, the sampling cup having a first end and an opposed second end and defining an interior cavity with the first end of the sampling cup defining an opening to the interior cavity and the second end of the sampling cup being closed, and the rod being composed of an electrically resistive material that maintains an electrical gradient of at least 50 kV per foot for at least one minute;
- collecting a molten glass sample in the interior cavity of the sampling cup;
- and
- unloading the molten glass sample from the sampling cup.
