Glass can be used to store things in the freezer. Glass containers can also be put in the freezer temporarily, to make a drink extra cold.

Glass works well to store food over time in a freezer. The glass will not break when it is frozen. However, it is recommended not to store liquids in a glass container. When liquids are frozen, they tend to expand; this expansion can place stress on the glass and may cause it to break. Instead, use a plastic bag that can expand with the liquid as it freezes.

If you opt to use a glass jar to freeze food, choose one that has a wide mouth and can be used for canning. These jars are designed to withstand extreme heat and cold temperatures.
