This invention was made to solve the above problem, and its gist is that a layer of a mixture of glazes that melt at the foaming temperature and inorganic particles that do not melt at the foaming temperature is provided on the ceramic foamable composition. Thereafter, the ceramic foamable composition is heated to a foaming temperature to foam to form a ceramic foam, and the glaze is melted to adhere a layer of glaze containing inorganic particles onto the ceramic foam. A method of manufacturing a ceramic foam is provided.

When a ceramic foamable composition, a mixture of glazes that melt at the foaming temperature and inorganic particles that do not melt at the foaming temperature are heated to the foaming temperature, the glazes melt and a layer of glazes is formed on the ceramic foam. It is formed. At this time, inorganic particles that do not melt are present in the glaze layer, forming a skin layer with a beautiful pattern. Furthermore, the inorganic particles prevent the formation of cracks in the layer due to volume reduction of the glazes as they melt.

That's what I do. Furthermore, the glazes of the present invention include all materials other than the above-mentioned glazes that have the same effect as glazes, such as inorganic materials that melt at a temperature below the foaming temperature of the ceramic foaming composition, or materials to which pigments are added. It is something that For example, a ceramic foamable composition without the foaming agent, a composition with the addition of something that lowers the softening temperature such as soda carbonate or borax, and a composition with a pigment added thereto can be used.

供給される。 A main raw material hopper 5 and a glaze hopper 7 are arranged above the conveyor 2, and a ceramic foamable composition 6 is sequentially dropped from the hopper 5, and a mixture 8 of glazes and inorganic particles is sequentially dropped from the hopper 5. , are each supplied onto the conveyor 2 to a substantially uniform thickness.

てもお互いに接着することが難しく、亀裂がその
まま残ることが多い。 Generally, when glazes melt, the volume decreases and cracks may occur in the layer, but in this invention, since the glaze contains inorganic particles that do not melt, this decrease in volume is small, and therefore This prevents cracks from forming and allows the glaze to flow and adhere to each other after melting, creating a beautiful glaze layer on the surface. These inorganic particles help form patterns in the glaze layer. If the glaze does not contain inorganic particles, the glaze will shrink significantly when melted, resulting in large cracks and difficulty in adhering to each other even when the glaze melts and flows out, and the cracks often remain.
又、この際、上から金網のようなもので押さえ
ていると、更に亀裂が少なく、しかも溶融した釉

In this invention, a layer of a mixture of glazes that melt at the foaming temperature and inorganic particles that do not melt at the foaming temperature is provided on the ceramic foamable composition, and the layer is heated to the foaming temperature, so that the foaming of the ceramic foamable composition is achieved. The heating process for melting the glazes is simplified and economical. Furthermore, since a mixture of glazes and inorganic particles that do not melt at the foaming temperature is used, a pattern of inorganic particles appears in the molten layer of glazes, forming a beautiful skin layer. Furthermore, since inorganic particles are present in the glaze, it is possible to prevent cracks from forming in the glaze layer.
