67000 Ball Qt Mason Jar Wmsuper

I have been using Ball #68100 wide-mouth, half-gallon Mason jars. They hold not only 2-quarts but even 2-liters and still allow airspace between the top of the contents and the rim or lid.

I needed 1-quart jars so I ordered Ball #67000 wide-mouth 1-qt jars. I was surprised to find, when they arrived, that not only could they not hold one quart of liquid with airspace above but they only held 30oz when filled to the rim.

I have since learned that "Ball" is a name licensed for use by multiple manufactures. The #67000 jars I purchased through Amazon were manufactured in the U.S.A. by Jarden and sold (through Amazon) by "All American General Store" which has since disappeared from Amazon's list of vendors. (All American General Store never did reply to my email complaint.)

A Ball 1-quart, wide-mouth Mason jar which I later purchased from a well known local merchant did, in fact, hold 32oz.

What a disappointment it was to learn that all Ball/Kerr metal canning jar lids are lined with the toxin BPA. I hope they're working on a lid that is 100% free of BPA, but in the mean time, if you're searching for lids without BPA, you might try Tattler lids. They are reusable and guaranteed to last a lifetime. There are others on the market as well.

I use these jars with a hand blender to make fabulous protein shakes. Since twelve of them come in the pack, I have found uses for the extra jars like storing coconut milk and soup. Does anyone know if you can put these in the freezer? Great product, highly recommend. Gets rid of the plastic.
