Photosensitive opal glass - Photosensitive opal glass

…If a glass composition that is easily crystallized is selected, a metal colloid is precipitated, and then the glass is further heat-treated near its softening point, crystals will precipitate from the metal colloid as crystal nuclei. This type of glass is called a photosensitive opal glass. If the solubility of the precipitated crystals in acid is significantly different from that of the glass phase, it is possible to selectively remove only the crystallized parts, i.e., the parts exposed to light. …
