A soda-lime-silica based privacy glass, having a visible transmission (Lta) of no greater than 25% and an infrared (IR) transmission no greater than 25%, includes the following colorants in addition to the base glass:total iron (expressed as Fe2O3): 0.1 to 1.0%cobalt oxide (e.g., Co3O4): 0 to 1,000 ppmsulfides (S2−): 0.0001 to 0.10%.In certain other embodiments the visible transmission may be higher, but low IR transmission is still realized.
