Abstract: A method of forming a glass sheet comprises: (a) forming a ribbon of glass from molten glass with a pair of forming rollers; (b) reducing horizontal temperature variability of the ribbon of glass to be 10° C. or less across 80 percent of an entire width of the ribbon of glass before the ribbon of glass cools to a glass transition temperature; (c) controlling a cooling rate of the ribbon of glass while the ribbon of glass moves vertically downward within a setting zone such that the ribbon of glass has a first average cooling rate before the ribbon of glass cools to the glass transition temperature and a second average cooling rate after the ribbon of glass cools to the glass transition temperature, the first average cooling rate being less than the second average cooling rate; and (d) separating a glass sheet from the ribbon of glass.

Abstract: Disclosed herein are testing apparatuses for testing stresses in substrates. The testing apparatus includes a base, a first plate coupled to the base, the first plate being movable relative to the base along a first axis, a second plate coupled to the base, the second plate being movable relative to the base and relative to the first plate along a second axis that is perpendicular to the first axis, a first actuator operable to move the first plate along the first axis towards or away from the second plate, a second actuator operable to move the second plate along the second axis relative to the first plate, and a controller operatively connected to the first actuator and the second actuator operable to control movement of the first plate and the second plate.
