Common Misconceptions About Canning Jars

Many people have misunderstandings about canning jars that can lead to unsafe practices. One common myth is that any glass jar can be used for canning. In reality, using jars specifically designed for canning is essential for safety and success. Regular glass jars, like those for pasta sauces, aren’t built to handle the pressure of canning!

Not all glass is equal: Canning jars are tested for heat and pressure, which regular jars are not.
Size matters: Using the right size jar ensures proper sealing and food preservation.
Check the seal: Always inspect jars for chips or cracks before use, as these can compromise safety.

One of the most important factors in choosing glass jars is ensuring they are BPA-free. BPA, or bisphenol A, is a chemical found in some plastics that can seep into food and has been linked to health risks. Luckily, most modern canning jars are made without BPA, but it's always wise to double-check! To learn more about selecting safe options, explore our article on BPA-free glass jars in Australia.
