The iridescence of ancient glass is symptomatic of the metal content. It is caused by exposure to damp earth or humid air over a long period of time. Carbon dioxide is dissolved in the moisture of the air of soil, forming carbonic acid. This in turn combines with the alkaline constituents of glass, bringing about decomposition of the surface. Glass which has been decolourized with manganese dioxide, such as this piece, displays more iridescence, coloured glass less.
