ULTRAVIOLET RAY-ABSORBING, COLORLESS AND TRANSPARENT SODA-LIME-SILICA GLASS

摘要

An ultraviolet ray-absorbing, colorless and transparent soda-lime-silica glass is disclosed, which glass is prepared by irradiating a cerium containing soda-lime-silica glass with light having wavelengths in far- to near-ultraviolet region and thereby reducing transmittance to light with wavelengths in the region of 300-400 nm.
