In Gear: Hacking Mason Jars
Or, 'A New Twist on an Old Standby'
In 1858 John L. Mason of New York City received a patent for improvements on jars meant for food storage and preservation, including a continuous raised spiral or thread around the mouth of the jar.
This type of glass storage jar was inexpensive, more or less infinitely reusable, easy to clean, and imparted no off flavors, as was the case with metal containers. It became a favorite of home cooks, and Mason’s new jars could be easily sealed, unsealed and resealed with screw-on metal caps—a dramatic improvement over existing methods, which included the fussy and messy practice of using hot wax to seal lids and stoppers into place.
Mason sold his patent the following year and, before long, countless manufacturers were making screw-top canning jars based on his model. Commonly known today as Mason jars or Ball jars (after the most prolific manufacturer of jars of this type), these iconic vessels remain popular for their original purpose, canning, as well as myriad other uses.
Additional Uses for Mason Jars
Attractive and reminiscent of simpler times, they make for quick centerpieces when filled with simple bouquets, marbles, rocks, candles, etc.
For storing dry goods like flour, cocoa powder, and salt, they are often more practical and airtight than most canisters marketed for such purposes.
Used as rugged, no-fuss tumblers, the jars have an uncanny way of imparting extra refreshment to summertime beverages like lemonade and iced tea (for which they also make practical serving and storage vessels).
