PROBLEM TO BE SOLVED: To enable various uses by forming a cavity in a wall face. SOLUTION: A cavity 2 led to the outside is formed in a wall face 1 of a biscuit firing product having water permeability. An opening hole communicating with the cavity 2 is made in the middle of the wall face 1. A part of the wall face of the biscuit firing product is coated with a glaze. When water or a liquid fertilizer is held in the cavity 2 formed in the wall face 1, the water or the fertilizer is permeated from the wall face at the inner side of the biscuit firing product having water permeability to the interior. Watering and manuring to a plant C potted in the biscuit firing product are not required. When water or cold water is put in the cavity 2 formed in the wall face 1, a wine-containing bottle stored in the biscuit firing product 1 can be cooled. When water or soil is put in the cavity 2, stems and roots of a flower can be introduced from the opening hole and decorated. When a glaze is applied to the outside of the bottom and the side of the biscuit firing product, the water and the liquid fertilizer can be prevented from leaking out. The amount of water supplied and the amount of applied fertilizer can be adjusted by regulating the width (area) to be coated with a glaze in the whole wall face of biscuit firing product. |
