National Mason Jar Day

National Mason Jar Day is celebrated on November 30 in the United States, honoring the iconic Mason jars that have achieved worldwide recognition. But what makes them so special that they have their own holiday?

History

In 1858, American tinsmith John L. Mason patented a machine that cut screw threads into glass jar lids and jar necks, creating a reliable, airtight seal. This invention revolutionized home food preservation, and Mason jars quickly became a must-have item for homemakers.

The jars are sold with lids separately; the lids are designed for single use and should be replaced after each sealing. Mason jars gained immense popularity in the United States during the 1960s and were used for everything from decorative centerpieces to storing smoothies and desserts, canning jams, and even serving ginger tea or lemonade through a lid with a special straw hole.
