ABSTRACT:
A basin for a forehearth of a glass-making furnace having an internal volume divided into upper and lower portions by an annular shoulder is described wherein the horizontal cross-sectional area of the upper portion is significantly greater than that of the lower portion. The base of the basin has a glass discharge outlet therein. In use, the discharge outlet is aligned with a relatively movable cylinder which acts as a flow metering valve. The cylinder can be rotated about its axis at a constant or adjustable speed, or the cylinder can be non-rotating and have a separately driven stirrer movable about it to prevent or reduce the formation of stagnant areas.
