The absorptive and refractive properties of additively colored glasses containing an absorptive metallic silver phase and a separated silver halide phase are altered by irradiating the colored glasses with visible light. Polarization effects and multicolored images can be produced.

Silver halide-containing photochromic glasses are rendered optically anisotropic by darkening with actinic radiation and irradiating with linearly polarized bleaching light. A photochromic glass so treated will be optically isotropic when it returns to the clear state, but may again become optically anisotropic when redarkened. Color adaptation results when darkened silver halide-containing photochromic glasses are irradiated with colored optical bleaching light.

A method of growing sapphire crystals from the melt wherein a porous alumina raw material is used to replenish the melt during growth. The porous alumina is subjected to a high temperature, low pressure environment to remove adsorbed water and oxygen which, if allowed to enter the melt, would result in poor monocrystals. A sequence of steps is provided which allows a simultaneous outgassing of one charge of porous alumina and a continuous replenishing of the melt with porous alumina of a previously outgassed charge. The previously outgassed charge of alumina must be handled in a system devoid of water and oxygen to avoid readsorption of the impurities.
