Abstract: A strengthened glass or glass ceramic sheet has a first major surface, a second major surface opposite the first major surface, an interior region between the first and second surfaces, an outer edge surface extending between the first and second major surfaces, and a thickness between the first major surface and the second major surfaces, wherein the sheet comprises a glass or glass ceramic and is thermally strengthened and wherein the first major surface has a roughness of more than 0.1 nm Ra and less than 500 nm Ra over an area of 10 μm×10 μm and wherein PP

Abstract: A method and system to dry crack-free and high strength skin including an inorganic binder of an average particle size (D50) in a range between 10 nm and 700 nm on a porous ceramic body. The method includes supporting the honeycomb body on an end face such that axial channels and outer periphery are substantially vertical. A gas is flowed past the honeycomb body substantially parallel to the axial channel direction, substantially equally around the outer periphery of the skin, to uniformly dry the skin to form a partially dried skin under mild conditions. Then the partially dried skin may be dried more severely resulting in rapidly dried crack-free and high strength skin.
