How to identify high borosilicate glass cups？

High borosilicate glass cups are a common type of cup that are known for their high temperature resistance, corrosion resistance, and durability. However, some consumers may not know how to identify high borosilicate glass cups and may unknowingly purchase low-quality glass cups from unscrupulous vendors. Here are some methods for identifying high borosilicate glass cups.

1. Price Identification

Another way to identify high borosilicate glass cups is through the price. High borosilicate glass cups are more complex to manufacture and use higher quality raw materials than ordinary glass cups, so their price is generally higher.

2. Appearance Identification

High borosilicate glass cups have certain characteristics, such as high glossiness, good transparency, and a smooth surface. When selecting high borosilicate glass cups, you can observe the external characteristics of the cup to determine whether it is a high borosilicate glass cup. At the same time, you can also determine the material by looking at the packaging and instructions of the cup.

3. Testing Identification

Finally, you can identify high borosilicate glass cups through testing. High borosilicate glass cups have high temperature resistance and corrosion resistance, and their performance can be tested through the following methods:

Hot water soaking test: Place the high borosilicate glass cup in hot water for a period of time. If the cup can withstand the high temperature without cracking or deforming, it is likely to be a high-quality high borosilicate glass cup.

Acid and alkali resistance test: Use an acidic or alkaline solution to test the corrosion resistance of the high borosilicate glass cup. If the cup shows no signs of corrosion or damage after the test, it is likely to be a high-quality high borosilicate glass cup.

In conclusion, identifying high borosilicate glass cups can be done through these methods. By following these methods, consumers can avoid being deceived by unscrupulous vendors and purchase high-quality high borosilicate glass cups.
