2019-5-21  The refractive index and density of silica Limestone were measured for various fictive temperatures. They both increase without any local maxima, as the fictive temperature increases up to 1550 C. From the relationship between the refractive index and the density, polarizability was estimated using the Lorentz-Lorenz formula.
