Can glass bottles be frozen in the refrigerator?
Glass bottles can be frozen in the refrigerator, but it should be noted that if the glass bottle is filled with water and the height of the water exceeds the mouth of the bottle, it can not be frozen in the refrigerator, because the volume of the water will expand after freezing and the glass bottle will burst . Overheated bottles should not be put directly into the refrigerator to prevent the glass from bursting due to excessive temperature changes .
