The short version: only certain glass types survive the freeze without drama.<\/p>\n<p>Two glass families dominate the freezing conversation: borosilicate and soda-lime.

Understanding this helps us read the glass a bit better when the temperature drops.<\/p>\n<p>Most home freezers anchor at about -18\u00b0C, a number that guides the conversation about safe storage. The cold tugs at liquid inside and the glass shares that memory, sometimes ending in micro-splits or stress lines.
