In embodiments, a precursor glass composition comprises from about 55 wt. % to about 80 wt. % SiO; from about 2 wt. % to about 20 wt. % AlO; from about 5 wt. % to about 20 wt. % LiO; greater than 0 wt % to about 3 wt. % NaO; a non-zero amount of POless than or equal to 4 wt. %; and from about 0.2 wt. % to about 15 wt. % ZrO. In embodiments, ZrO(wt. %)+PO(wt. %) is greater than 3. When the precursor glass composition is converted to a glass-ceramic article, the glass-ceramic article may include grains having a longest dimension of less than 100 nm.
