Glass cups are now commonly used items in every household. Have you ever encountered a situation where a glass cup broke on its own? This article will help you understand the common reasons for glass cup breakage.
1. Internal defects: Glass cups may have internal defects during the manufacturing process, such as tiny air bubbles or uneven crystallization. These defects can cause the glass cup to suddenly break under slight pressure or temperature changes.
2. Thermal stress: When a glass cup is exposed to uneven heating conditions, such as pouring hot water into a cold glass cup or cold water into a hot glass cup, it can create temperature differences on the surface and inside the glass, leading to thermal stress. This thermal stress can cause the glass cup to break.
3. Mechanical stress: Glass cups may experience impacts, collisions, or bending stresses during use. If these stresses exceed the glass’s tolerance, the glass cup may break.
4. Accumulation of minor damage: Glass cups may undergo multiple instances of minor damage, such as tiny scratches or chips. These damages can gradually accumulate and weaken the strength of the glass. Under certain conditions, these minor damages can cause the glass cup to break on its own.
In summary, glass cup breakage is usually caused by factors such as internal defects, thermal stress, mechanical stress, or the accumulation of minor damage. To prevent this, avoid extreme temperature differences during use and minimize situations where the cup may be subjected to collisions. If the glass cup is damaged, has bubbles, or is uneven, it is advisable not to use it.
