Abstract
Onggi, which is described as a breathing pottery, has strongly influenced the traditional food culture in Korea. In this study Onggi is compared to porcelains including celadon and white porcelain to analyze the sources of pore formation. The differences in starting materials are examined for chemical and mineralogical compositions, particle size and distribution. The gas permeability of the fired samples is correlated to the matrix microstructure. The broad particle size distribution and high iron oxide content of Onggi are revealed as the major cause for the pore formation. Open pores are formed with large particles in the Onggi body while closed pores have a high iron oxide concentration. The Onggi body with increased open pores leads to the high gas permeability.
