Those are not tempered glass so they are likely to shatter if shocked
when frozen. And one should never freeze any liquid in glass, liquid
expands while freezing and can easly shatter glasss containers,
especially those untempered jars. There are a huge variety of plastic
containers suitable for freezing, very reasonably priced and
reusable. But you may safely use those jars for refrigerator storage.
I use mayo jars for my pickled jalapenos... good I saved a bunch as
all mayo is packaged in plastic jars now.
