Antimony is a highly toxic element, present at remote locations in our planet, and is used in some glasses to enhance its optical performances. Antimony is not present in common glasses, such as: Normal window glass; glass bottles; drinking glasses; or glass lamps etc. Antimony in glass was recommended by EU RoHS recast committee to be banned in EU. At that time, dispensation was granted to optical glass and solar glass because the European industry had then represented that it was not possible to make solar products without it. However, glass manufacturers have been hard at work since then trying to eliminate antimony from solar glasses where it is considered necessary to use it. This article examines the breakthroughs recently made by Indian-based Gujarat Borosil in eliminating antimony from solar glass.
