Understand the unique advantages of high borosilicate glass bottles

Many people have encountered problems such as ordinary glass cups shattering when boiling water is poured in and storage bottles turning foggy and white after long-term storage of sauce. The root cause lies in the inherent performance defects of ordinary sodium-calcium glass. Ordinary glass is mainly made of sodium-calcium oxide, with a boron content of less than 1%. Its internal molecular structure is unstable, and it expands and contracts significantly when the temperature changes. Even a small temperature difference can generate internal stress, eventually leading to cracks and explosions. It has poor chemical stability. If it comes into long-term contact with acidic or alkaline food, the surface of the glass is prone to corrosion and the release of harmful metal ions.

High borosilicate glass has a silicon dioxide content of over 78% and a boron oxide proportion of 12% to 13%. Its special formula significantly reduces the coefficient of thermal expansion to only one-third of that of ordinary glass, maximizing its thermal shock resistance. In daily use, it can quickly switch from sub-zero temperature to boiling water temperature without stress cracking on the bottle body, making it suitable for various scenarios such as microwave ovens, steamers, and refrigerators. At the same time, the material has strong chemical inertness and is resistant to acid and alkali corrosion. It will not undergo chemical reactions when used to store medicinal wine, jam, vinegar, or high-temperature soup. It can be used with confidence for storage in mother and baby products and food.

In terms of physical texture, the high borosilicate has a light transmittance of over 90%, is transparent and clean without any impurities, the bottle body is smooth and not easy to accumulate stains, and is easy to clean. Ordinary glass has a relatively low light transmittance and contains many impurities. It is prone to yellowing and fogging after long-term use. Although high borosilicate is more expensive, its service life is much longer than that of ordinary glass. It is less likely to be damaged by bumps and knocks, and has a higher cost performance for long-term use.

When making a purchase, do not easily believe the verbal labels of the merchants. Give priority to choosing products with formal production qualifications and test reports to avoid buying counterfeit and inferior imitation high borosilicate glass bottles. Take into account both usage safety and service life.
