低温与高温对玻璃强度的影响是不同的，一般认为随着温度的升高会使缺限处积聚更多的应变能，增加破裂的概率。当温度高于200℃时，由于玻璃黏滞性流动增加，使微裂纹的裂口钝化，缓和了应力作用，从而使玻璃强度加大。玻璃的使用温度范围较广，温度对玻璃强度影响的机理目前尚未探明，根据在零度（-273℃）至500℃范围内的测试，强度较低点位于200℃左右。

  这里还要讲玻璃的热稳定性，即玻璃保持不破坏能经受的非常大温度差，也就是玻璃耐急冷急热的温度差。显著膨胀系数越小，其热稳定性就越好，U型玻璃的Δt约110℃左右，换句话说玻璃加热到350℃时，如果瞬时降至240℃时就会破裂。微晶玻璃因为膨胀系数较高，所以其热稳定性也高。通常急热时，玻璃表面产生压应力不易坏，而急冷时，玻璃表面产生张应力就易坏。玻璃的热稳定性还与玻璃成分、制品厚度、是否淬过火等有关。

The effect of low temperature and high temperature on the strength of glass is different. It is generally believed that with the increase of temperature, more strain energy will accumulate at the gap and the probability of fracture will increase. When the temperature is higher than 200 ℃, due to the increase of viscous flow of glass, the cracks of microcracks are passivated, and the stress is relieved, so the glass strength is increased. Glass has a wide range of service temperature, and the mechanism of the influence of temperature on glass strength has not yet been explored. According to the test in the range of zero (- 273 ℃) to 500 ℃, the low point of strength is about 200 ℃.

Here we also talk about the thermal stability of glass, that is, the very large temperature difference that the glass can withstand without damage, that is, the temperature difference that the glass can withstand rapid cooling and heating. The smaller the significant expansion coefficient is, the better the thermal stability is. The Δ t of U-shaped glass is about 110 ℃. In other words, when the glass is heated to 350 ℃, it will break if it drops to 240 ℃ instantaneously. Glass ceramics have high thermal stability because of its high coefficient of expansion. It is not easy to damage the glass surface when it is hot, but it is easy to damage the glass surface when it is cold. The thermal stability of glass is also related to glass composition, product thickness and whether it has been quenched.
