Foods such as Kimchi, soybeans, grains, and bean and red pepper paste, are placed in Jangdok (or Onggi) earthenware jars which are then placed on the Jangdokdae.

The jars are called hangari (항아리)[4] or onggi (옹기).

[5] This place is commonly found directly near traditional Korean houses, more precisely near the kitchen.

Sunshine and ventilation are key aspects in the location choice, so that foods can be preserved and kept fresh.

The similar terraces of royal palaces were called yeomgo (염고) and were supervised by a court lady, called janggo mama (장고 마마).
