LARGE ROMAN GLASS FLASK
S O L D
Measurements: 14.7 cm – height, 9.8 cm – width
Description: An ancient Roman flask in light translucent glass and displaying attractive rainbow iridescence. The flask consists of a wide, concave base that expands to its widest part towards the bottom of the body, a conical body, a short, widening neck and an everted 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.
