Abstract: The invention relates to a device capable of rotating about an axis (6), for the refining and homogenization of glass, comprising a receptacle (1) intended to receive the molten glass to be treated, a vacuum compartment (2) and at least one glass outlet orifice (5, 19), furthermore including a conveying means (7, 8, 17, 18) for conveying the molten glass from the feed receptacle (1) to the vacuum compartment (2). It also relates to a process for manufacturing substrates employing the device according to the invention, and to the substrates thus manufactured.

Abstract: The invention relates to a plant and to a process for manufacturing a glass, comprising the production of a main stream of a liquid main glass, by a main plant that includes a main furnace, and the production of an auxiliary stream of a liquid auxiliary glass, by an auxiliary plant that includes an auxiliary furnace having a submerged burner, the auxiliary stream being smaller than the main stream, the auxiliary glass having a composition different from that of the main glass and the two streams then being mixed to form a single total stream of the final glass. The auxiliary furnace especially provides the function of coloring the main glass so that the final glass is a colored glass. A highly homogeneous and bulk-colored flat glass may thus be manufactured by an installation having short transition times.
