PROBLEM TO BE SOLVED: To provide a carbonized earthenware which is prepared by adhering, to the surface of an earthenware, a carbonized material consisting mainly of carbon by utilizing a dry distillation gas generated in the carbonization treatment of an organic substance and which is especially useful as food and drink vessels or cooking utensils; and to provide a manufacturing method thereof. SOLUTION: The carbonized earthenware is manufactured in such a way that a carbonized material consisting mainly of carbon is adhered to an earthenware by arranging a solid organic material and an earthenware having minute pores and a water absorption of 3 % or more in a carbonization chamber and heating the inside of the carbonization chamber to 500-800°C with a high-temperature burning gas to dry-distil the solid organic material and simultaneously to bring a thermal decomposition gas produced from the solid organic material into contact with the earthenware. On the surface of thus yielded carbonized earthenware, the carbonized material adheres along the minute pores, coloring the whole surface black. COPYRIGHT: (C)2005,JPO&NCIPI
