NOT FREEZER SAFE! Two exploded in the freezer.
on June 29, 2014
UPDATE: I originally gave these 1 star because they were described by Amazon as freezer-safe, and I had multiples explode in my freezer, despite leaving room for expansion (see review below). However, Amazon has removed this description, so I am giving the product a better rating as these jars are still great for non-freezer purposes. If you are looking for freezer containers, the smaller sized wide-mouth jars are great and are freezer-safe.
For those who use Ball jars for freezing: The Amazon description stated that they are freezer safe. I bought these locally (MUCH better price), and a chart on the box says that the quart size is not freezer safe. I took my chances hoping that this Amazon description was right...they aren't. I've had two explode in the freezer, even though I left a decent amount of room for expansion. The Amazon description says that they are freezer safe, but the box specifically says that the quart size is not. Other (smaller) sizes of the Ball Wide Mouth Mason Jars are truly freezer safe. I have been using the smaller sizes for over a year without any problems. The quart size is the only one I've had a problem with in the freezer.
In summary, the Amazon description is incorrect. The quart size is NOT freezer safe. All other smaller sizes of the Ball mason jars are freezer safe (according to the chart on the box, and personal experience.)
