FIELD: chemistry.
SUBSTANCE: invention proposes the glass with high permeability in visible range and/or practically transparent or neutral color. The glass contains iron oxide (0.02-0.10%) in combination with erbium oxide (Er5) (0.02-0.15%), SO3 (0.25-0.40%). The glass may contain small amount of cobalt oxide and cerium oxide. The glass possesses permeability in visible range that equals at least 90%, permeability value a* from -0.8 to +0.8 and permeability value b* from -0.8 to +0.9.
EFFECT: creation of the glass with high permeability in visible range without resorting to extremely pure i.e. practically not containing iron raw materials.
