Abstract:

A glass article including any one or several of SiO.sub.2, Al.sub.2O.sub.3, B.sub.2O.sub.3, Li.sub.2O, SnO.sub.2 and a fusion line. The glass article can also include a liquidus viscosity less than or equal to 100 kP. In some embodiments, the glass article includes, on an oxide basis, from 60 mol % to 74 mol % SiO.sub.2, from 7 mol % to 18 mol % Al.sub.2O.sub.3, from 3 mol % to 16 mol % B.sub.2O.sub.3, from 0 mol % to 6 mol % Na.sub.2O, from 0 mol % to 5 mol % P.sub.2O.sub.5, from 5 mol % to 11 mol % Li.sub.2O, less than or equal to 0.2 mol % SnO.sub.2.
