I've got a big blue canning jar that I knew was too big to be a quart jar, so I filled it up with water and it held 6 cups or 1 1/2 quarts? Isn't that a little unusual? Does the book list this bottle. It's a "slope shouldered" Ball Mason jar (it has those two words on the front), and a screw top that accepts one of those zinc caps or lids.
