Used to store pickles.

During the Republic of China, a pickle jar was a container used to store pickles. It was usually made of materials such as ceramics or glass and had the characteristics of acid resistance, moisture resistance, and good sealing. At that time, pickles were an important preserved food, and pickle jars were the main tool for storing pickles. By placing the pickles in the pickle jar, the freshness and quality of the pickles can be better maintained, and air and moisture are reduced during storage, slowing down the rate of rot and deterioration of the pickles in the pickle jar. In an era when food resources were scarce, pickle jars have also become one of the indispensable kitchen utensils in people's daily lives.

In addition, due to different types of pickles and different storage needs, in order to better meet the different needs of families, pickle jars have also appeared in different specifications and sizes, which can be large or small, with different shapes, and are flexible application.
