We are inseparable from water glasses in our lives. Many people have consulted our glass cup manufacturers and asked whether double-layer glass cups can be kept warm? In fact, it depends on the manufacturer. Some glass cups are of poor quality, so it is not easy to keep warm, and the double-layer glass cups we produce have a very good thermal insulation effect, so you can rest assured. Today, the editor also summarizes the method of purchasing a double-layer glass with good thermal insulation effect. You can learn how to choose a high-quality thermal glass together. Let's take a look! glasscookware .

(1) The purchase of an insulated double-layer glass depends on the quality of the filter.

In addition, the finer the filter mesh, the better, which can effectively filter the residues in the tea leaves, keep the tea leaves from leaking, and increase the purity and taste of the tea water;

(2) Purchasing an insulated double-walled glass depends on the seal. Double-layer glass, whether there is a leakage problem is generally related to the sealing ring in the lid. High-quality glass generally uses food-grade silicone pads, which are very consistent with the rotation and twisting of the cup body, have good sealing performance, and ensure good thermal insulation aging;

(3) When buying a double-layer glass, look at whether the appearance is defective. The double-layer glass is mainly composed of a lid, a body and a bottom. It can be observed whether the twist of the lid matches, and whether there are bubbles and scratches on the body. For the bottom of the cup, thickening is generally used to increase the weight of the cup. The thicker the bottom of the cup, the more stable and firm the quality, the stronger the impact resistance and the stronger the bump resistance.
