The body is marked at regular intervals giving the impression of a reticulated web of ribs. Glass objects worked in this fashion are called hot-worked as the surface is manipulated and decorated whilst it is still hot and in a malleable state with the aid of tools (eg metal tongs) with circular or square ends.
Original size 11.2 cms high.
