The Effect of Low Temperatures on Pyrex
Pyrex is a popular brand of glassware commonly used in cooking and food storage. It is known for its durability and resistance to thermal shock, which makes it a versatile option in the kitchen. However, it is important to understand how Pyrex behaves under extreme temperatures, especially when it comes to the freezer.
When Pyrex is exposed to low temperatures, such as those inside a freezer, it can potentially break. This is because drastic temperature changes can cause stress on the glass, leading to cracks or shattering. The main concern with Pyrex in the freezer is not the glass itself, but rather the expansion and contraction of substances contained within it.
When liquids, such as a soup or sauce, are frozen in Pyrex containers, they expand as they solidify. This expansion can put additional pressure on the glass, increasing the risk of breakage. Similarly, when hot Pyrex dishes are rapidly cooled in the freezer, the contrasting temperatures can cause the glass to fracture.
To minimize the risk of Pyrex breaking in the freezer, it is important to follow some guidelines. Avoid placing hot Pyrex dishes directly into the freezer; instead, allow them to cool at room temperature for a while. When freezing liquids in Pyrex containers, make sure to leave adequate headspace to allow for expansion. Additionally, it is recommended to use Pyrex designed specifically for freezing, as they may be more resistant to temperature changes.
| DOs | DON’Ts |
| – Allow hot Pyrex dishes to cool before putting them in the freezer | – Put hot Pyrex dishes directly into the freezer |
| – Leave adequate headspace when freezing liquids in Pyrex containers | – Fill Pyrex containers to the brim when freezing liquids |
| – Use Pyrex designed specifically for freezing | – Use old or chipped Pyrex containers in the freezer |
In summary, while Pyrex is generally durable and resistant to temperature changes, it is important to handle it correctly when placing it in the freezer. By following the recommended guidelines and using Pyrex designed for freezing, you can minimize the risk of breakage and enjoy the benefits of this versatile glassware.
