Abstract

A stirring system for molten glass having a stirring vessel and a stirrer; and a method for homogenizing glass melts. The stirrer has a shaft and at least one stirring element, and the stirring vessel has at least two baffles extending from an inner circumferential surface. The stirring element and baffles are formed in such a way that insertion of the stirrer into the stirring vessel requires at least one translatory movement of the stirrer in relation to the stirring vessel, at least one subsequent or simultaneous relative rotation of the stirrer in relation to the stirring vessel, and a further translatory movement of the stirrer in relation to the stirring vessel. In an operating state, the stirrer is rotatable in the stirring vessel.
