Mason Glass Jar 350ml With Metal Lid

A Mason jar, also known as a canning jar, is a type of glass jar with a two-part metal lid used for preserving and canning food. These jars have been popular for over a century and are widely recognized for their distinctive design and functionality. Mason jars were originally invented and patented by John Landis Mason in 1858, and they have since become an iconic household item. Here are some key features and uses of Mason jars:

Two-Part Lid: Mason jars come with a two-part metal lid consisting of a flat metal disc and a screw-on band. The flat disc creates an airtight seal when properly sealed, which is essential for preserving and canning foods.

Glass Body: The main body of the Mason jar is made of clear glass, which allows you to see the contents inside. These jars come in various sizes, including pint, quart, and half-gallon options.

Preservation: Mason jars are primarily used for home canning and preserving a wide range of foods, including fruits, vegetables, jams, jellies, pickles, and sauces. The airtight seal created by the lid prevents spoilage and keeps the food fresh.

Storage: In addition to canning, Mason jars are used for general food storage, such as holding dry goods like grains, pasta, and spices. They are also suitable for refrigerating and freezing food items.
