I am hoping you get this message. I am pleased to find that Ball canning jars are safe. I am an avid home canner. I have heard that Natures Harvest jars are made by Ball as well, but would this mean that the jars are consistent with their safety? Also, I have some vintage canning jars with glass lids and zinc rings, but they are not Ball brand. I think Canadian? Do you know if these are safe? I don’t can in them, but I do store dried foods. It got me thinking it probably isn’t wise especially if they aren’t lead free, or low in lead.
Forgive me, the brand of jars are Golden Harvest which I believe are manufactured by Ball.
I think it’s really interesting that the vintage blue jar is lead free, but the newer blue jars contain lead!
Which makes me wonder if all the vintage ball jars I have are lead free or not. I have both blue and clear vintage ball jars.
