Have you heard of “high borosilicate glass tea set”? In recent years, it has gradually entered our lives and become the preferred tool for many people to drink water and make tea. But is this glass really as safe as it is said to be? What is the difference between it and a regular glass cup? What should we pay attention to when using it? Today, let’s talk about this topic together and help you uncover the mysterious veil of high borosilicate glass cups.
What is a high borosilicate glass cup
High borosilicate glass is made by utilizing the conductive properties of glass at high temperatures, melting the glass by heating it inside, and processing it through production processes. Due to its coefficient of thermal expansion of (3.3 ± 0.1) * 10-6/K, it is also known as “borosilicate glass 3.3″. It is a special glass material with low expansion rate, high temperature resistance, high height, high hardness, high transmittance, and high chemical stability. It was widely used in laboratory equipment manufacturing as early as the late 19th century due to its advantages of heat resistance, acid and alkali resistance, and impact resistance.
The key difference between high borosilicate glass and ordinary glass is that it can withstand drastic temperature changes. This means that you can safely pour boiling water into it without worrying about sudden explosion. Compared to ordinary glass that shatters with a ‘pop’ sound, high borosilicate glass cups are much safer. Especially in the circle of friends who enjoy making tea and drinking hot water, it is very popular.
How safe is a high borosilicate glass cup?
When it comes to safety, many people are most concerned about whether it will release harmful substances. We can breathe a sigh of relief here – according to the latest scientific research in 2024, high borosilicate glass will not release harmful substances under normal usage conditions. Because its chemical composition is very stable, it is different from plastic products that “fade” and “lose their flavor” when used at high temperatures.
It is worth mentioning that high borosilicate glass does not contain harmful chemicals such as bisphenol A (BPA), which makes it more suitable for healthy drinking water than plastic cups.
Of course, no material is perfect. Although high borosilicate glass cups are resistant to heat and impact, they are not indestructible. If accidentally dropped, broken glass shards can still pose a safety hazard. Therefore, we suggest handling with care in daily use, especially for the elderly and children, who need to be more careful when operating.
What are the advantages of high borosilicate glass cups
The material structure of ordinary glass cups is relatively simple, and their heat resistance is also relatively poor. Have you ever experienced the dilemma of pouring hot water into a regular glass and suddenly hearing a “click” sound? That’s because ordinary glass has a high coefficient of thermal expansion, which makes it prone to stress cracks when exposed to high temperatures. In contrast, the thermal expansion coefficient of high borosilicate glass cups is very low, and even if boiling water is suddenly poured in, they are not easily broken.
In addition, high borosilicate glass cups have another commendable advantage – they are more durable. After long-term use, ordinary glass cups may have small scratches, becoming a breeding ground for bacteria. High borosilicate glass cups have higher hardness, are less prone to scratches, and have a longer service life.
But even the most durable things need to be taken good care of. If you want your high borosilicate glass to live a hundred years, daily cleaning and maintenance must not be taken lightly. It is recommended to avoid using hard tools such as steel wire balls to clean glass cups, and to use soft cleaning cloths as much as possible to avoid leaving scratches on the surface.
Details of using high borosilicate glass cups
High borosilicate glass cups may look “indestructible”, but we still need to pay attention to some details when using them to truly achieve safe drinking water:
1. Handle with care: Although it has good impact resistance, glass is still glass and there is still a danger once it breaks.
2. Regular cleaning: Don’t wait for the bottom of the cup to accumulate thick tea stains before washing it! Keeping clean not only extends its lifespan, but also prevents the growth of bacteria.
3. Avoid using in extreme environments: Although high borosilicate glass cups are resistant to high temperatures, do not heat them directly on an open flame. No matter how much they can resist, they cannot withstand such turmoil!
4.Gentle cleaning: Do not use a steel wire ball to brush the cup, as it will leave unsightly scratches.
If you have elderly or children at home, it is recommended to pay more attention when using high borosilicate glass cups, as safety comes first. Overall, high borosilicate glass cups are a relatively safe, environmentally friendly, and durable choice, especially suitable for friends who enjoy drinking hot water and tea. But when using it, we still need to develop good habits to ensure safety.
如果你家里有老人或者孩子，建议在使用高硼硅玻璃杯时多加注意，毕竟安全第一。总的来说，高硼硅玻璃杯是一个相对安全、环保、耐用的选择，尤其适合喜欢喝热水和茶的朋友。但使用时，我们还是要养成良好的习惯，确保安全。
