Iridescent glass daisy button.
15mm cast glass button, the detail is in high relief, approximately 200 years old.
(iridescence) caused by alkali (soluble salt) being leached from the glass by slightly 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 an iridescent appearance.
Four lights @90 degree intervals, sitting on a mirror.
White balance was set to incandescent which has given the button a blue cast, purely for the effect.
found in a leet ditch that dated from the late Georgian period (early C19th)
