3. In addition, the firing method is not the conventional method of firing in an oxidizing atmosphere or reprocessing the surface of the fired product, but by reducing and melting the material in a reducing atmosphere and oxidizing it during the cooling process to create a thin surface layer. The method used was to obtain a glow through the interference of light between the layer and the light layer below.
