Mason Jar

A Mason jar is a type of glass jar used primarily for preserving and storing food. Invented in the mid-19th century by John Mason, its design features a screw-on lid and a rubber seal that create an airtight environment, allowing for safe canning and long-term storage of fruits, vegetables, and other food items. Mason jars have become popular beyond food preservation; they are often used for drinks, crafts, and home decor due to their simple, versatile design. They are associated with DIY culture and sustainability, promoting the idea of reducing waste and supporting homemade goods.
