Abstract
Embodiments of a method for pair bending glass articles is provided herein. In the method, a first glass article and a second glass article are stacked to form a stack. The first glass article includes a first surface, a second surface that opposes the first surface, and a first composition having first annealing and softening temperatures. The second glass article includes a third surface, a fourth surface that opposes the third surface, and a second composition having second annealing and softening temperatures. The annealing temperatures are within 35° C. of each other and are at least 550° C. The softening temperatures are within 35° C. of each other and are at least 750° C. In the method, the stack is placed on a mold, and the stack is heated to a sagging temperature such that a shaped stack is formed.
