The body color of glass comes from the materials and manufacturing method used. A mixture of
minerals, iron and sand creates glass, and by manipulating these minerals, the Romans
discovered how the color of the glass could change. The coloring of this glass today is
accidental, occurring by mere chance. After being buried deep in soil for many years, the
chemical makeup of the glass has changed, giving this ancient glass an iridescent look. When
immersed in water the iridescence will actually go away, and will reappear once dry.
