A laminate glass article is provided that includes: a core glass layer comprising a first coefficient of thermal expansion (CTE); and a plurality of clad glass layers, each comprising a first primary surface, a second primary surface in contact with the core glass layer and a second CTE that is lower than the first CTE of the core glass layer. The difference in the first and second CTE is about 10 x 10-7/⁰C to about 70 x 10-7/⁰C. Further, each of the core glass layer and the clad glass layers comprises a viscosity from 109.0 to 1014.0 Poise from about 550⁰C to about 700⁰C. |
