The Myth of Freezing Glass
There is a common myth that you should never put glass in the freezer. It is often believed that glass will shatter or crack when exposed to extreme temperature changes.
However, this myth is unfounded. Glass is actually a highly durable material and can withstand freezing temperatures without any issues. The main concern with freezing glass is not the glass itself, but the contents inside.
When liquid inside a glass container freezes, it expands. This expansion can put pressure on the glass walls and potentially cause it to crack or shatter. This is why it is important to leave enough headspace in any glass container when freezing liquids.
Another important factor to consider is the type of glass. Not all glass is created equal. Some types of glass, such as tempered glass, are more resistant to thermal shock and are less likely to break when exposed to extreme temperatures.
It is also important to note that rapid temperature changes can increase the risk of glass breakage. If you want to freeze glass containers, it is recommended to gradually cool them down by placing them in the refrigerator first before transferring to the freezer.
In conclusion, the myth that you should never put glass in the freezer is just that – a myth. While it is important to take precautions when freezing glass containers, such as leaving enough headspace and using the right type of glass, freezing glass is generally safe and can be done without any issues.
