Unformatted text preview: The refiner receives the glass as it passes through the throat. This glass is pure and the refiner performs the “fining” process and removes air bubbles by forcing them to float to the surface. Forehearths are ceramic lined troughs that convey glass from the refiner into glass container forming machines. The temperature of the glass is stabilized here so that it is the optimum temperature for forming containers. When glass enters the forehearth, it is about 2350°F and when it leaves it is about 2000°F. Colorant can also be added here, in addition to being added in the Batch House. Up to eight forehearths can be on one glass furnace, allowing each forehearth to design a different container simultaneously. Glass flows out of the forehearths through “feeders”, or “spouts”.
