Description: An ancient Roman bottle in light green clear glass and displaying silvery iridescence. The bottle consists of a concave base, an rounded body, and a wide, flaring mouth with a rolled rim. The word iridescence comes from Iris, the Greek goddess of rainbows and refers to rainbow-like colours seen on glass. It is caused by alkali being leached from the glass by acidic water and then forming fine layers that eventually separate slightly or flake off, causing a prism effect on light bouncing off and passing through the surface which reflects light differently, resulting in a rainbow-like appearance such as the one on this flask. This piece has the colour of ancient glass in its natural state - bluish green that resulted from the iron oxide present in the silica or the sand.
