ABSTRACT:
The basic shape of the molten glass fining apparatus of the present invention is preferably either an elliptical or a somewhat rectangular shape such that the flow is more uniform and the bubbles have less distance to rise to the surface. A novel baffle design is also shown. The present invention improves the fining capability of the apparatus without increasing the cost of construction materials. In fact, the cost may be reduced.
