This is a classic example of a lead crystal ale glass dating to the second half of the 18th century.
The bowl is conical, tapering in towards the short, solid stem. There is a globular junction where the stem meets the plain foot. The latter is broad with a folded rim, and a central rough pontil mark.
The bowl has been engraved on one side with a stylised hop with associated leaves and tendrils. On the opposite side of the bowl are two ears of barley, which are mirror images of each other, their stems crossing over to form a single motif.
It has a height of approximately 15.2cm, with a diameter across the rim of about 5.8cm and across the foot of about 6.7cm.
It has a liquid capacity (to the brim) of 100ml.
It has an unwrapped weight of 90g.
It is in excellent condition, with no chips or cracks. The bowl and stem are not entirely straight so there is a minor lean (which can be observed in the pictures). This is a manufacturing artefact and is part of the charm of these historic pieces.
