PROBLEM TO BE SOLVED : To provide a method of controlling the evaporation of a liquid constituent component stored in a ceramic container, capable of controlling the evaporation of a liquid constituent component such as beverage stored in the container by changing the components of the ceramic container, and provide a ceramic container. SOLUTION : The evaporation of a liquid constituent component stored in a ceramic container is controlled by incorporating an oxide effectively radiating far-infrared rays as a constituent component in a ceramic container comprising clay, quartz, feldspar and the like as main components. As an oxide effectively radiating far-infrared rays, a transition metal oxide (iron oxide, manganese oxide or the like) or a white metal oxide (titanium oxide, zinc oxide or the like) as a main additive and further a rare earth oxide (neodymium oxide, cerium oxide or the like) for coloring are each incorporated in an amount of 5 to 40 mass%.
