Most common glass has other substances to vary its properties. Guide glass or flint glass is much more "fantastic" as the improved refractive index brings about noticeably much more specular reflection and enhanced optical dispersion. Introducing barium also increases the refractive index. Thorium oxide presents glass a significant refractive index and low dispersion and was formerly Utilized in producing substantial-high-quality lenses, but due to its radioactivity has become replaced by lanthanum oxide in contemporary eyeglasses.
