製作可能である。 Since the firing kiln tool of the present invention has a supporting column inserted into the hole 3 and is firmly fixed, its stability is sufficient even when assembled in multiple stages, and the object to be fired can be stably assembled directly. Because it can be used, there is no occurrence of sagging. Furthermore, since the firing kiln tool of the present invention is made of ceramic foam, it has excellent heat resistance, has a small absorption heat capacity, and has little energy loss. Furthermore, it can be easily manufactured by molding or the like.

体を載置することができる。 In the present invention, the firing kiln tool may be supported at four points on a plane as shown in FIG. 2, or may be supported at three points as shown in FIG. 3. 4 is an object to be fired. The latter is suitable for baking with a circular plate placed thereon. The support section of the kiln tool for firing may be in the shape of a polygonal pyramid, and in this case there is an advantage that the insertion direction of the kiln tool is determined and no misalignment occurs. Also, the upper part may be provided with a flat part on which a shelf board etc. is placed only in one direction as shown in Figure 1, but this flat part can also be provided in one to three other directions. In that case, a plurality of objects to be fired can be placed in multiple directions.
