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.
