One of a group of four miscellaneous wine glasses; this one with a waisted bell bowl and honeycomb moulding, on an airtwist stem.
Honeycombing was sometimes moulded into glasses to introduce more visual interest.
However, this particular glass already has the added interest of an airtwist stem which was developed by English glass blowers in the early 18th Century.
Once a blob of molten glass was attached to the bowl, it was pierced by nails and as the stem was drawn out and twisted, the pattern was formed and could be varied by changing the number, size and shape of the nails.
