Collector's Edition. 1910-1923. New. Perfect mason. Near the turn of the 20th century, the famous Ball Blue color was created when the minerals in the sand used to make the jars resulted in an unexpected aqua color. These aqua jars were beautiful and became popular for preserving and storing jams, jellies and other recipes. Today, with the new Ball Collector's Edition jars, you can re-live history with a vintage design, color, and logo from a bygone era. Over 130 years of research testing and advancing the art of fresh preservation go into every product we sell. www.freshpreserving.com. Connect with Us: Facebook. Twitter. Pinterest.
