ABSTRACT:
A method for treating the surface of the inner wall of a furnace, said inner wall being lined with ceramic fibers, involves placing a source generating an alkali component in a furnace for firing a material into a product, in which at least the inner wall is lined with a ceramic fiber body, and heating the interior of the furnace to vaporize the alkali component, thereby impregnating the surface layer portion of the ceramic fiber body with the thus vaporized alkali component.
