Exhibit Antiques has dated this piece to the 1750s.
A very rare small example of an 18th-century wrythen flami ale glass dating to c1730.

With a conical bowl, this wrythen-technique differs from typical wrythen moulding as an extra layer of glass is used, giving a deeper texture and more definition. A flattened ball knop sits above a conical foot.

We cant recall seeing another small example like this.
