Abstract:

An article that includes: SiO.sub.2 from 40 mol % to 80 mol %; Al.sub.2O.sub.3 from 1 mol % to 15 mol %; B.sub.2O.sub.3 from 5 mol % to 50 mol %; WO.sub.3 from 1 mol % to 15 mol %; WO.sub.3 plus MoO.sub.3 from 1 mol % to 18 mol %; SnO.sub.2 from 0.01 mol % to 1 mol %; and R.sub.2O from 1.1 mol % to 16 mol %. The R.sub.2O is one or more of Li.sub.2O, Na.sub.2O, K.sub.2O, Rb.sub.2O and Cs.sub.2O. R.sub.2O minus Al.sub.2O.sub.3 ranges from +0.1 mol % to +4 mol %.
