Bell beaker (glass)
The bell beakers are a heterogeneous group of glasses from the early Middle Ages. What they have in common is the disc-shaped base, which, in contrast to most early medieval glasses, allows them to stand, and the more or less high goblet shape. In addition, they are usually constricted to the ground and have a bulbous lower wall.
The bell beakers are, like all early medieval glasses, mostly light green, yellow or olive green or blue green. As a rule, these are natural colors that can be traced back to contamination of the quartz sand required for production with iron oxides. The color could also be achieved in a targeted manner, for example by adding copper oxides. The glasses are also often and very heavily riddled with bubbles, black soot particles and streaks. This could be an intended type of ornament.
