What is a wide mouth earthenware jar?

A wide mouth earthenware jar is a type of pottery vessel that is typically made of clay and fired at a high temperature. It has a wide opening, which makes it easy to fill and empty, and a narrow neck, which helps to keep the contents from spilling. Earthenware jars are often used for storing food, such as grains, rice, and flour, and can also be used for fermenting vegetables or making pickles. They are also sometimes used for decorative purposes.
