Glass opal is created by melting silica, which is the primary component of natural opal, along with other materials like soda and lime to lower the melting point. This mixture is heated until it forms a molten glass, which is then cooled to create a solid piece. The production process often includes the addition of colorants or other additives to mimic the natural opalescence and play-of-color found in genuine opals. Unlike natural opals, glass opal does not form through geological processes and lacks the unique internal structures that give natural opals their characteristic appearance.
