The hazard is that mayonaise, jelly, etc jars are meant for one time use and are usually of thinner glass than a "Mason" jar. Some of the ready-to-eat spaghetti sauces are in "real" canning jars, most particularly Classico and, I believe, Five Brothers. Another problem with mayo jars and such is that the lid ridges aren't made for canning jar lids and rings so you don't get a good seal. Your "heat and serve" jar is probably made of heavier glass since it is meant to be heated. You can also usually tell if jellies and jams have gone "off" whereas it's a bit tricker with green beans, carrots and such veggies. I've had green beans that were properly prepared, properly pressure canned, and properly stored that went bad. Soon as I popped the lid I could smell them, think maybe the lid didn't seal all the way around. There's risk in everything you do and thank goodness there is or I wouldn't be able to make a living as a safety consultant. <VBG> George
