Thank you for your question! A scientist at Corning Incorporated provided us with an answer. His response is quoted below. I have also provided a few institutions that you might contact for additional information.

Begin Quote:

Glass only breaks when tensile stresses cause a critical flaw to propagate as a crack. It isn't low temperature per se that would cause glass to break, but a temperature change, usually a decrease, that could cause temporary stresses that would be large enough to propagate a crack. For certain kinds of glass products, this is seen in a test called thermal downshock, where a hot glass article is plunged into, for instance, ice water. The stress generated is a function of the temperature difference, the thermal expansion coefficient of the glass, and the geometry (mostly thickness and shape) of the article. As the surface cools quickly and contracts, tensile stresses can be large enough to cause breakage. Companies that make bakeware pay attention to this.

Glass containers are used for liquid nitrogen and perhaps for liquid helium, so there isn't anything about uniform low temperature that would cause a problem.

  1. I don't understand how this answers my question#confused):

  2. I believe the answer they gave comes down to "Glass does not shatter when it gets cold if not subjected to thermal stresses. If it is cooled evenly and slowly, it can be cooled to -273 C without cracking."

  3. Um... I just wanna know the temp...

  4. So, bottom line if a box of wrapped empty glasses in a car trunk in "freezing temperatures" will not crack UNLESS it's brought down in a heated area "too fast...???

  5. Not sure what you guys dont understand, it's pretty clear. Glass will NOT break/shatter in any specific cold temperature unless it goes from hot to cold too fast. Meaning it could be -200F and still be fine, but if it dropped from (hypothetically speaking) 60F to -200F in 3 seconds it is very possible to break/shatter. If you're looking for specific temperatures, it has different variables like what kind of glass, timing of temperature drop and actual temperatures, so that's too broad of a question to specifically answer.
