Another reason for glass breakage is improper thawing. You may use a microwave oven to thaw the food inside the jar, but keep it on a low setting. While some glass jars are tempered to withstand heat, sudden changes in temperature can cause them to break.

There are three simple steps to freeze food inside a mason jar.

  • Pour the food into the jar. You may use a wide mouth funnel or a ladle to do so. For liquids, always leave a clearance of at least an inch or two, to allow the food to expand on top while freezing.
  • Cool the food. Freezing hot food will cause the jar to break. You may immerse the jar in a cold water bath to speed up the cooling. You may also cool the food first before pouring it onto the glass. Make sure it is completely cooled. You may label the jars so it’ll be easier to identify the food and the date it was prepared.
