Victorian herringbone air trap satin glass vase

From Sunday's antiques fair, comes this coolly elegant piece of Victorian satin glass.
It measures 20.5 cm tall, & is made from three layers of cased glass - clear over shaded pale blue, with a white interior. The vase features air trap decoration in a herringbone pattern & has an applied clear thorn handle. It has a rough, snapped pontil mark on the base.
Silken smooth & so refined!
