Lucky for us, this handy chart can help you keep track of all the Ball jar logos. There are about eight different logos in total, starting in the 1880s and finishing in the present day.
A collection of Mason jars filled with preserved foods. A Mason jar, also known as a canning jar, preserves jar or fruit jar, is a glass jar used in home canning to preserve food. It was named after American tinsmith John Landis Mason, who patented it in 1858. The jar's mouth has a screw thread on its outer perimeter to accept a metal ring or ...
Prior to 1933, Ball was the largest domestic manufacturer of home canning jars. In 1939 it manufactured 54% of all the canning jars made in the US. A drop in demand for the jars during the 1930s led the Ball brothers to begin manufacturing other types of jars and bottles for commercial use, and eventually expanding into other lines of business.
John Landis Mason (c. 1832 in Vineland, New Jersey – February 26, 1902) was an American tinsmith and the patentee of the metal screw-on lid for antique fruit jars commonly known as Mason jars. Many such jars were printed with the line "Mason's Patent Nov 30th 1858". [1] He also invented the first screw top salt shaker in 1858.

Food is placed in glass canning jars and placed in ...
Canning is a method of food preservation in which food is processed and sealed in an airtight container (jars like Mason jars, and steel and tin cans). Canning provides a shelf life that typically ranges from one to five years, [ a ] although under specific circumstances, it can be much longer. [ 2 ]
Cans imported from the US often have odd sizes such as 3.8 L (1 US gallon), 1.9 L (1/2 US gallon), and 946 ml (2 US pints / 1 quart). In the UK and Australia, cans are usually measured by net weight. A standard size tin can holds roughly 400 g; though the weight can vary between 385 g and 425 g depending on the density of the contents.
Food is processed in Weck jars using the water bath canning technique, not a pressure canner. During the canning process the lids are secured by the clips which can be removed once the processing is complete and the jars have cooled since the lid is being forced shut by atmospheric pressure.
