ABSTRACT:
A method and apparatus for protecting the underface of ceramic or refractory tiles and the refractory rollers forming the advancing plane of a roller tunnel kiln during the firing and cooling of the tiles, in which to at least part of the underside of the tiles is applied a protective layer of a refractory material in suspension by an applicator, such as rollers, during advancement of the tiles by a conveyor into the kiln so that the protective layer is interposed between the underface of the tiles and the refractory rollers of the kiln preventing the tiles when heated and cooled from adhering or being welded to the refractory rollers.
