Art nouveau iridiscent green vase, probably Wilhelm Kralik's, around 1905.

Green glass, gold green and blue violet powder melts.
Spiral wall decoration, strongly iridescent.
The pontil is not polished.
Height 10.2 cm.
I was told that this vase is probably Wilhelm Kralik's, Eleonorenhain (Bohemia), around 1905.
The first picture displays the vase backlighted to show its beautiful green colour, which otherwise looks opaque with iridiscences.
