Hi,
Another mystery (to me anyway

) vase.
Incredibly tall at 18" (46cm) :shock: and has a clear outer casing over bright red. It would appear the blue inner sandwiches a white core - if viewing the rim edge-on it shows blue/white/red.
The dramatic effect at the base is a trailed ribbon of glass over the surface. Large snapped pontil mark at base.
:shock: click to zoom :shock:

Here are two photos showing the base in more detail:
