An article includes SiO2 from about 40 mol % to about 80 mol %, Al2O3 from about 1 mol % to about 20 mol %, B2O3 from about 3 mol % to about 50 mol %, WO3 plus MoO3 from about 1 mol % to about 18 mol % and at least one of: (i) Au from about 0.001 mol % to about 0.5 mol %, (ii) Ag from about 0.025 mol % to about 1.5 mol %, and (iii) Cu from about 0.03 mol % to about 1 mol %, and R2O from about 0 mol % to about 15 mol %. The R2O is one or more of Li2O, Na2O, K2O, Rb2O and Cs2O. R2O minus Al2O3 ranges from about −12 mol % to about 3.8 mol %.
