Patent number: 6403509Abstract: 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.Type: GrantFiled: February 23, 2001Date of Patent: June 11, 2002Assignee: Guardian Industries Corp.Inventors: Gary Seldon Cochran, Anthony Vincent Longobardo, Ksenia Alexander Landa, Leonid Mendel Landa
