Abstract:
A glass composition includes greater than or equal to 69.0 mol % SiO2, greater than or equal to 7.0 mol % Al2O3, greater than or equal to 14.0 mol % R2O, and an absolute value of a slope of a line extending between a first endpoint and a second endpoint less than or equal to |0.020|. The first endpoint is a Young's modulus at a fictive temperature of the annealing point temperature and the second endpoint is a Young's modulus at a fictive temperature of the strain point temperature, and the slope is a change in Young's modulus (GPa) per 1° C. change in fictive temperature. R2O is a total amount of alkali metal oxides and includes at least two alkali metal oxides. A glass article and consumer electronic product are also disclosed.
