Can Square Glass Jars Handle Thermal Shock in Sterilization?

They are often used in households and restaurants to preserve and store food, such as jams, sauces, pickles, etc. These jars are convenient, and they can brighten the kitchen. But have you ever wondered if square glass jars withstand quick temperature changes when we wash them?

Testing Square Glass Jars for Hotness:

Huiyu Packaging set out to find if our square glass jars can withstand extremely hot or extremely cold temperatures during the cleaning process. We did some experiments to see just how sturdy the jars are as they heat up.

What Happens to Glass Jars When They Get Hot and Cold?

In our testing, we found that the square glass jars were prone to cracking or breaking when they were subjected to sudden temperature changes. It is known as thermal shock, which occurs when the glass expands or contracts rapidly due to hot or cold conditions.

Can Square Glass Jars Survive Extreme Heat?

After many trials, we learned that square glass jars can withstand only a certain magnitude of temperature shock during dishwashing. They can withstand some moderate heat — say, being placed in a warm (not hot) oven — but may not be safe with very hot things, such as boiling water or steam.

Experimenting to See How Durable Square Glass Jars Are:

Knowing the Boundaries of Square Glass Bottles:

Ultimately, square glass jars are plenty strong and come in very useful as storage squares, but they have limitations, if you expect to run very hot water over them while cleaning, or very cold ice cubes. In order to maintain the safety of your food and keep your jars in top condition, it’s important to do the right cleaning and make sure the jars aren’t part of any temperature shocks.

An overall note You should consider how sturdy square glass jars are when you’re using them for cleaning. Use for food storage, but be gentle with them and steer clear of extremely hot or cold conditions. You can prolong the period of using square glass jars by being aware of their limits and being careful. As always, be safe when canning your food in glass jars!
