A high LTa, low UV and IR transmittance grey glass employing as its colorant portion iron (Fe2O3/FeO), erbium (Er2O3) and, optionally, titanium (TiO2). Enhanced effects are achieved by forming separate prebatch mixes, one of which includes rouge, metallic Si (optional), SiO and sand, the other including the remainder of ingredients, which after separate formation are then admixed to form the final, overall batch.
