Sometimes the coating is called Irid, Iris, Iridized or Iridescent. 

• Iridescent glass is made by adding metallic compounds to the glass or by spraying the surface with stannous chloride or lead chloride and reheating it in a reducing atmosphere.
• Ancient glasses appear iridescent from the reflection of light off of many layers of weathering.
