A method of manufacturing a glass-ceramic article, comprising:
- heat-treating a glass to grow crystals of MxWO3, where 0<x<1 and M comprises H, Li, Na, K, Rb, Cs, Ca, Sr, Ba, Zn, Cu, Ag, Sn, Cd, In, Tl, Pb, Bi, Th, La, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, and/or U,
- wherein at least prior to the heat-treating the glass comprises, in terms of constituent oxides, SiO2, B2O3, Al2O3, WO3, and R2O, where R2O is a sum of alkali metal oxides Na2O, K2O, Cs2O, and/or Rb2O in the glass, and
- wherein the Al2O3 and R2O in mol % of the glass at least prior to the heat-treating are such that −10≤(R2O−Al2O3)≤0.1.
