The last couple years has pushed home canners to resort to using questionable home canning supplies and methods. One of these questionable supplies is reusing commercial jars. Is this possible?
Commercial jars are not designed to be reused in home canning. There are many types of glass and not all glass jars are tempered to withstand the home canning process. This could result in broken jars, spoiled food, and food loss.
Because the lids used on commercial jars cannot be reused, home canning 2-piece lids may not fit the mouths of commercial jars properly. Therefore, lids will not seal properly.
The “Atlas” brand shows up on some of todays commercial jars. These jars used to be made by the Hazel-Atlas Company, but they are no longer in business. The “Atlas” name used on commercial jars is for marketing purposes only.
