Many glass manufacturers produce double-layer ice buckets. Vacuum double-glazed glasses are usually hand-blown. The double-layered glass provides thermal insulation and can also store ice. During the blowing process, if the middle layer is not a vacuum, the outer layer of the glass has a vent hole. This is to vent the gas out of the glass to prevent it from deforming and exploding. After the production is finished, the hole is sealed. So there is gas in the middle of the two layers.
