Object Lessons: Canning Jars

July 29, 2014

Napoleon Bonaparte declared, “An army marches on its stomach,” and in 1795 he offered 12,000 francs to anyone who could liberate his men from the monotony of dried, salted, smoked, and pickled food. It took about 15 years for a French confectioner to produce a ceramic jar that preserved fresh fruit and vegetables using boiling water, cork, and sealing wax. (Napoleon kept his word, though we don’t know if he honored inflation.) 

The cork and sealing wax method, however, wasn’t always reliable, and it was impossible to see the contents of a sealed ceramic jar. Some 50 years later a New York tinsmith named John Mason worked out these drawbacks. Mason patented his simple, threaded-zinc, screw-top glass jar and emblazoned “Mason’s Patent Nov 30 1858” on every example that issued from his factory for years, making his name synonymous with a well-kept pantry. He did this just in time for the Civil War, eventually adding the removable rubber ring that we know today. Later, World War II played an important part in canning history as citizens in America, Britain, and Canada were encouraged to grow Victory Gardens, preserving the bounty for the lean winter months of powdered food and substitutes.

Since then, a variety of jars have proven invaluable in the canning process, some with screw tops, others with hinged and clipped lids or clamps. Today the canning jar is put to countless uses, including as an ideal, plastic-free receptacle for nuts, grains, and tonight’s leftovers. 

Five to buy

Above: In 1900, Johann Weck introduced his glass jars with lids that clip on the exterior, preventing the contents from coming in contact with metal. Weck’s wide-mouth jars also provided a more efficient way of adding and subtracting contents than the more traditional bottleneck jar. A set of 12 Weck Mini Mold Jars (pictured) is available for $34.95 at Williams-Sonoma.
