Chung-Ju San Bang Co., Ltd.

Succeeding to the soul of our ancestors
  who enjoyed the sweet scent of tea, keeping the courtesy, we make the porcelains
  with the ocher soil, which is traditionally used for making the pottery, and
  the natural glaze; therefore, they can provide you with the excellent preservation
  of food.

Unfortunately, there was a hard time for
  the traditional pottery. It was forced to give the seat of honor to the modern
  pottery including the glass and plastic pottery but we can retain the honor
  of the traditional porcelain through using the authentically traditional method
  containing the soul of ancestors - harmonizing the ocher, ash with the fire.
  On the basis of this technical foothold, we promise you to give the best product
  in this field.
