A brush having antimicrobial characteristics that inhibit bacterial growth. The antimicrobial agents, compounds or chemicals are embedded in either the body or bristles or both of the brush. Further, the present invention is a method of manufacturing a brush having antimicrobial characteristics that inhibit bacterial growth. An antimicrobial additive is incorporated in resin concentrate form into the amorphous zones of the molecular structure of the polymer from which brush handles are injection molded, thereby incorporating the antimicrobial agent into the brush handle.

In order to avoid deposition of evaporating alkali compounds on an inner surface of a hollow glass body during thermal processing to form a glass container from the hollow glass body, an overpressure is provided in the hollow glass body during the thermal processing. Either rinsing the hollow glass body with a gas, such as air, or at least partially closing the glass body at one end so that sufficiently rapid pressure equilibration is avoided, can provide this overpressure. The glass containers made by these methods are especially suited for food or pharmaceuticals because they have a reduced alkali release from their inner surfaces, for example at most about 2.0 mg / l sodium oxide.
