Glass-ceramic compositions and laminated glass articles incorporating the same

A method comprising:

• fusing a glass core layer having a core coefficient of thermal expansion CTEC to at least one glass clad layer having a pre-ceramming coefficient of thermal expansion CTEPC within about 20% of CTEC to form a laminated glass article, the at least one glass clad layer comprising:
• from about 60 mol. % to about 75 mol. % SiO2;
• from about 5 mol. % to about 10 mol. % Al2O3;
• from about 2 mol. % to about 20 mol. % alkali oxide R2O, the alkali oxide R2O comprising Li2O and Na2O;
• and
• from 0 mol. % to about 5 mol. % alkaline earth oxide RO, the alkaline earth oxide RO comprising MgO, wherein a ratio of Al2O3 (mol. %)/(R2O (mol. %)+RO (mol. %)) is less than 1;
• a nucleating agent selected from the group consisting of TiO2, ZrO2, P2O5, and combinations thereof;
• and
• heat treating the laminated glass article to ceram the at least one glass clad layer, thereby reducing the coefficient of thermal expansion of the glass clad layer to a post-ceramming coefficient of thermal expansion CTEAC that is greater than or equal to 20×10−7/° C. and less than or equal to about 70×10−7/° C. and less than the core coefficient of thermal expansion CTEC, wherein a difference between the core coefficient of thermal expansion CTEC and the clad coefficient of thermal expansion CTECL is greater than or equal to 20×10−7/° C., a major crystalline phase of the at least one glass clad layer being Li2Si2O5.
