Zusammenfassung:	PROBLEM TO BE SOLVED: To evaluate and test sintering, heating-insulating, and molten metal penetration resisting properties, and the like of a molten-metal container tapping hole filler, under conditions approximating actual operations, by performing evaluation and tests which take into account the influence of temperature gradient between a nozzle and a molten metal. SOLUTION: Refractory containers 10, 20 each of which is open at its lower end are filled with filler 11, 21, and the openings in the lower ends are closed with a thin metallic foil that is easily melted. The lower parts of the refractory containers 10, 20 are vertically soaked into a molten metal 41, and are raised from the molten metal after being soaked in the metal for a predetermined time. Next, the refractory containers 10, 20 are parted, and the inner condition of the filler is observed to detect molten metal penetration state and sintered layers. When the refractory containers 10, 20 with a single or plural thermocouples 13, 23 inserted therein are used, temperature distribution with respect to the soaking direction is detected.
