Exhibit Antiques has dated this piece to the Before 1700 period.
The material is remarkably well preserved on one side of the vessel. A nearly-transparent glass with the slightest of pale green and amber hues and is almost colourless when viewing through the preserved area.

The wheel-cut decoration on the vessel wall has been well executed with continuous horizontal striations, the central pair are more defined shallow grooves while the outer lines are surface level and appear to be tooling marks.
