Abstract: An apparatus for preheating a batch (12) of glass cullet which is preferably enriched with raw materials for glass production, comprising a bunker (14) preferably having flow ducts for the passage of warm (off)gas. To discharge the preheated batch of glass cullet from the bunker, the apparatus has one or more discharge worms (26), by way of which the batch of glass cullet can be conveyed to at least one outflow opening (28) in the base region of the bunker (14).

Abstract: An apparatus for preheating a batch (12) of glass cullet which is preferably enriched with raw materials for glass production, comprising a bunker (14) and flow ducts (22) formed therein, wherein the bunker (14) comprises a plurality of flow ducts (22) which are arranged vertically, and if appropriate offset, one above another and extend at an angle in relation to the vertical, in particular horizontally, wherein each flow duct (22) is composed of a profiled section (34) for forming an upper half thereof and also a heap of the batch (12) of glass cullet which is formed underneath the profiled section and forms the lower half of the flow duct (22), and wherein the profiled section has at least two limbs (36a, b) which laterally delimit the space between them.

Abstract: Foodstuffs filled in glass containers undergo a change in taste under the influence of light. In order to combat such changes in taste the glass according to the invention contains vanadium pentoxide. Since pure vanadium pentoxide is relative expensive, the invention proposes a way of using a mixture of vanadium pentoxide and phosphorous oxide which is available as an economical aggregate. This type of glass is preferably used to accomodate foodstuffs. The glass containing vanadium pentoxide and phosphorous oxide is particularly suited for bottles to hold beer. Such bottles exhibit particularly effective light protection properties when they are made of so-called white glass.
