This is a classic example of a lead crystal gin or small wine glass dating to around 1820.
The trumpet-shaped bowl is cut in the lower two-thirds with ten panels. The base of the bowl is thickened and sits on a broad discoid collar and a further smaller collar. Below this, the stem is of double-capstan form. The foot is plain, slightly domed, and has a central polished pontil.
It has a height of approximately 11.1cm, with a diameter across the rim of about 6.0cm and across the foot of about 5.9cm.
It has a liquid capacity (to the brim) of 80ml.
It has an unwrapped weight of 110g.
They are in good condition, with no chips or cracks, although there are some wear and tear scratches and enclosed bubbles commensurate with age and use. There is also a small bump on the rim which is probably where the rim was cut during manufacture.
