This disclosure is directed to techniques for utilizing various sensors and models to evaluate glass as it progresses through the tempering process in order to ensure that the tempered glass is of a proper quality. If, according to any of the various sensor measurements, the tempered glass is not of a proper quality, the system may automatically adjust one or more settings in any of the various components of the system in order to bring future panes of tempered glass back to having the proper quality. The system can measure for any number of glass characteristics or system characteristics, including edge quality, vertical flatness, haze, washing process variables, thermal imaging, distortion, blower information, production data, and furnace process data.

The present invention relates to a laser cutting technology for cutting and separating thin substrates of transparent materials, for example to cutting of display glass compositions mainly used for production of Thin Film Transistors (TFT) devices. The described laser process can be used to make straight cuts, for example at a speed of >1 m/sec, to cut sharp radii outer corners (<1 mm), and to create arbitrary curved shapes including forming interior holes and slots. A method of laser processing an alkaline earth boro-aluminosilicate glass composite workpiece includes focusing a pulsed laser beam into a focal line. The focal line is directed into the glass composite workpiece, generating induced absorption within the material. The workpiece and the laser beam are translated relative to each other to form a plurality of defect lines along a contour, with adjacent defect lines have a spacing of 0.1-20 microns.

A method of manufacturing and treating a glass article wherein the treatment of the article includes directing a flow of plasma, such as a flow of plasma comprising an atmospheric pressure plasma jet, toward an edge surface of the article. Such treatment can reduce a density of particles on an edge surface of the article. Such treatment can also increase the edge strength of the article.

The present disclosure relates to a process for cutting and separating arbitrary shapes of thin substrates of transparent materials, particularly tailored composite fusion drawn glass sheets, and the disclosure also relates to a glass article prepared by the method. The developed laser method can be tailored for manual separation of the parts from the panel or full laser separation by thermally stressing the desired profile. The self-separation method involves the utilization of an ultra-short pulse laser that can be followed by a CO.sub.2 laser (coupled with high pressure air flow) for fully automated separation.
