DEFINITION

Classification: 264/600

HEAT POLISHING (E.G., GLAZING, ETC.) OF INORGANIC ARTICLE SURFACE OUTSIDE OF MOLD:

(under the class definition) Processes for producing inorganic article by firing outside of the mold at temperatures sufficiently high to cause only a surface of the article to become melt smoothed or melt rounded without substantial loss of original self-sustaining shape of the overall article.

SEE OR SEARCH THIS CLASS, SUBCLASS:

15, for processes of spheroidizing or rounding solid particle.

129, Note (1), for a discussion of shaping and coating combinations.

332, for fusing or melting inorganic materials, per se, in a mold or employing a mold.

609, for particular or specific manner of positioning, arranging, or conveying of plural blocks, tiles, or bricks (e.g., stacking, utilizing spacer, etc.) during sintering, vitrifying, or drying.

680, for process of otherwise shaping or treating block, tile, or brick combined with sintering, vitrifying, or firing outside the mold.

65, Glass Manufacturing, appropriate subclasses for processes under the class definition which include glass fusing or vitrifying.

427, Coating Processes, for processes including the combination of (a) firing and coating, or (b) nominal molding, significant coating, and firing; regardless of the sequence of the respective steps. However, combinations of (a) significant molding, firing, and coating, or (b) nominal molding and nominal coating are classified in Class 264; regardless of the sequence of the respective steps.
