ABSTRACT:
The present invention relates to a sheet which may be used in firing ceramic faced base plates, glass faced base plates and metal faced base plates. The sheet comprises a combustible sheet such as a pulp paper and a coating layer coated on at least one surface of the combustible sheet. The coating layer comprises a powder of a material with a high melting point and a powder of carbon which may be formed separately from the layer comprising the powder of a material having a high melting point. The coating layer comprising the powder of carbon effectively prevents shrinkage of the sheet during firing, and thus prevents adhesion between adjacent stacked base plates and between the base plates and the supporting base. The sheet of the present invention further provides a layer of a uniform breadth which prevents the formation of undulations and pin-holes in the base plates during firing.
