Canning Jars to bottle syrup?

[wiam]

My opinion on heating glass is larger, as in qt or larger, does not need to be heated. I think on smaller glass there is as much or more glass than syrup, so it cools glass too fast.

I gave up a few years ago on the 1/2 gallon and gallon jugs. With the economy the way it is people just are not buying them from me. Quarts sell the best. As far as heating the mason jars it doesnt matter how you do it. As long as they come out clean and sterile. I know a few guys that dont even heat them up and have no problems with them sealing, my concern has always been them not being hot enough long enough to kill any mold growing bacteria.
