I was given a box of Ball quart sized canning jars that are a pretty blue color.

My question is.....are they safe to can stuff in? Dh thinks they may not be safe to can with because of the color (?) like it may be lead or something. (sorry if this is a dumb question)

I assume they are old jars because I've never seen ones like that before. They look just like the new kind of Ball canning jars that you can buy except for the color.

I tried looking on Yahoo for any info but couldn't find anything, so I was hoping someone here would know.

Thank you!
