I went to an estate auction yesterday and picked up 73 canning jars that was a mix of qt. and pt. with both the wide mouth and regular mouth. There was also 24 - 2 qt. jars. The entire lot was $5.00. It was a great deal but what in the world do you do with 1/2 gallon jars? :dunno: They don't fit in the water bath or the pressure canner. Anyone have any experience with these monsters?
