The design of double glasses greatly reduces the thermal conductivity of the cup body, and can effectively play the role of heat insulation and scalding proof in use.
The double-layer glass can improve the comfort of the use of the cup by adopting the principle of double-layer structure, and also improve the glass insulation effect. The double-layer glass has good aesthetic value besides humanized design. Transparent manufacturing materials combined with double-layer structure almost sublimate the tea drinking water into a dynamic art line. Yes.
Many glass manufacturers have double-decked ice buckets. Vacuum double-decked glasses are usually hand-blown, double-decked glasses have heat preservation and insulation functions, but also can keep ice. If the middle of the lattice is not a vacuum cup, then there is an air outlet at the bottom of the outer layer, in order to prevent gas from blowing process. The cup is deformed and burst, and the seal is finished after completion of production, with gas in the center.
