ABSTRACT:
A process for the batchwise production of glass performs melting, refining and discharging steps in electrically heated identical vessels, wherein at least the refining step is conducted during rotation of a vessel, and discharging of the refined glass takes place while the vessel is at rest. By using several vessels, which are either mobile or which are connected with one another by movable spouts, feeding of molten glass to a distributing channel for further processing is done continuously. Vessels according to the invention have electrodes for heating purposes; outlet port sealing arrangements; and ports for applying over-pressure or a vacuum to control glass exit speed. Blast pipes may be disposed in proximity with outlet ports in order to improve flow of the glass melt by introducing blasts of an inert gas.
