[PROBLEMS] To eliminate the need for preliminary preparation for freezing the cold insulation material, to prepare ice, to be lightweight, and to easily cool or cool beverages or foods even on the go, and can also keep warm. A ceramic cooler. A ceramic cooler 1 according to the present invention comprises a porous ceramic 2 having a large number of pores on its surface, and a ceramic product that cools an object to be cooled by vaporizing a liquid (mainly water) contained in the pores. It is a cooler. Since this ceramic cooler is formed of porous ceramics, it is lightweight and easy to carry. In addition, it is not necessary to prepare in advance for freezing the cold insulation material, it is not necessary to prepare ice, and beverages or foods can be easily cooled or kept cold simply by containing water in the pores. Furthermore, since it is made of porous ceramics, it is possible to keep warm. [Selection] Figure 5 |
