Abstract: The embodiments described herein relate to glass articles that include mechanically durable glass compositions having high liquidus viscosity. The glass articles may include glass compositions having from 50 mol. % to 80 mol. % SiO2; from 7 mol. % to 25 mol. % Al2O3; from 2 mol. % to about 14 mol. % Li2O; 0.4 mol. % P2O5; and less than or equal to 0.5 mol. % ZrO2. The quantity (Al2O3 (mol. %)-R2O (mol. %)-RO (mol. %)) is greater than zero, where R2O (mol. %) is the sum of the molar amounts of Li2O, Na2O, K2O, Rb2O, and Cs2O in the glass composition and RO (mol. %) is the sum of the molar amounts of BeO, MgO, CaO, SrO, BaO, and ZnO in the glass composition. A molar ratio of (Li2O (mol. %))/(R2O (mol. %)) may be greater or equal to 0.5. In embodiments, the glass composition may include B2O3. The glass compositions are fusion formable and have high damage resistance.
