Abstract: Coated glass articles for a glass-ceramic ceramming process including a parting agent coated on a surface of the glass article. The parting agent coating can comprise an aqueous dispersion comprising amorphous silicon dioxide agglomerate particles and a dispersant. The parting agent coating can be dried to forming a parting layer for glass articles in a glass stack for a ceramming process that transforms the glass articles into glass-ceramic articles.

Abstract: A method of separating an edge strip of a sheet of brittle material using a handheld sheet edge strip separation device is provided. The method includes sliding an edge receiving channel of a separation body of the sheet edge strip separation device over an edge portion that includes an edge of the sheet of brittle material. The edge receiving channel has a fixed width and is integrally formed as part of the separation body. The sheet edge strip separation device is rotated to provide a force over an area of the edge portion. The edge strip is separated from a quality portion of the sheet of brittle material with the glass edge strip located in the edge receiving channel.
