The difference between Amber Jar single layer and double layer

The Amber Jar produced by glass manufacturers can be divided into single-layer Amber Jar and double-layer Amber Jar. As the name suggests, the glass manufacturer divides it into two layers when making glasses, while the single-layer Amber Jar is the opposite. Two-layer glass and one-layer glass, of course, this is only the most intuitive difference. This article mainly introduces the difference between the two from the following aspects and comprehensively.

From the manufacturing process:

The two are similar in production process. They are generally processed with high-quality borosilicate crystal glass tubes and fired at a high temperature of over 600 degrees. They are adaptable to temperature changes and are not easy to burst. The double-layer Amber Jar has an additional insulation layer. The glass manufacturer has a vent hole on the outer layer of the cup. In order to help the gas escape and prevent the cup from deforming and bursting, the hole is sealed after the production is completed. There is gas in the middle. If it is a vacuum, the cup will make a louder sound when it breaks, and it will blow up glass fragments, which can easily injure people. That's not good.

In terms of heat preservation effect

After the lid is closed, the double-layer Amber Jar has better heat insulation than the single-layer Amber Jar. The double-layer Amber Jar adopts a double-layer heat insulation structure, which reduces the thermal conductivity of the cup body, not only does not burn hands, but also has a certain degree of heat preservation. The single-layer Amber Jar does not have an intermediate heat insulation design, and the heat is dissipated relatively quickly. Pouring hot water will feel hot.

In terms of capacity:

With the same volume, the single layer has a larger capacity and the double layer has a smaller capacity.

The difference in usage:

The double-layer Amber Jar produced by glass manufacturers is mostly equipped with a tea drain. For those who like to drink tea, it is suitable to make various kinds of tea; single-layer Amber Jar is mostly used for drinking ice water or cold drinks. A cold drink can't be so cool. Double-layer and single-layer, different people have different needs, just choose the one you like.
