Mason’s Patent Nov. 30th 1858 – DuPont

Provenance: Jerry McCann Collection

Here is a very rare proprietary brand Mason’s Patent Nov. 30th 1858 jar with DUPONT embossed on the reverse. This occurs within a horizontal outline oval which was the DuPont logo for this time period. This brand would be in reference to the DuPont gunpowder and chemical works in Delaware. The jar has a ground mouth and a zinc cap.

DuPont was founded in 1802 by Éleuthère Irénée du Pont, using capital raised in France and gunpowder machinery imported from France. He started the company at the Eleutherian Mills, on the Brandywine Creek, near Wilmington, Delaware, two years after du Pont and his family left France to escape the French Revolution and religious persecution against Huguenot Protestants.

The company began as a manufacturer of gunpowder, as du Pont noticed that the industry in North America was lagging behind Europe. The company grew quickly, and by the mid-19th century had become the largest supplier of gunpowder to the United States military, supplying one-third to one-half the powder used by the Union Army during the American Civil War. The Eleutherian Mills site is now a museum and a National Historic Landmark.

There are a number of variations of this DUPONT jar. In many cases, the jar maker is unknown while in other examples we see base markings indicating where it was made.

We have pictured as support images a pint, quart, and half-gallon. One variation has an embossed “C” with a small, solid arrow or triangle on both ends between the arched “MASON’S” and “PATENT” embossed copy. In some examples, there is illegible ghosting below the “-C-” which looks to be the CFJCo monogram for Consolidated Fruit Jar Company. Others depict variations of the “DUPONT” logo. One has a backward “N.”

We have many other Mason’s Patent Nov. 30th, 1858 jars in our museum. Too many to list here so take a look and read about the history, the patent, and John Landis Mason.
