There are many kinds of ceramic ware used in the Indian kitchens for various purposes.
Traditionally ceramic jars were used to store pickles like mango, lime and amla (gooseberry) etc. They are a part of the traditional kitchenware with a specific colouring and form. They have a cylindrical shaped jar with a curved neck. A lid with a knob sits inside the wide neck of the jar. They are available in various sizes too.
The pickles stored in these jars never spoil, possibly because of the properties of the ceramic material used
