Wine Glass - Round Funnel Bowl with Air Twist Double Knop Stem - Late 18th Century (16.5 cm high)
Location: Lichfield District Council
Accession number: GL07
A wine glass with round funnel bowl and double knop stem, manufactured in England in the late 18th century.
The glass has a plain, undecorated round funnel shaped bowl. The stem of the glass is decorated by twisting threads known as a multi-spiral air twist. Two rounded bumps known as knops are also located on the stem of the glass.
The glass sits on a conical foot with an unground pontil. This pontil is a bump which was left over from the manufacturing process and marks the point where the glassblower's pipe was attached to the glass.
The air twist style of stem manufacture occurred within the British glass making industry between 1730-1780. The effect was achieved by piercing the base of the glass bowl with a circle of nails whilst the glass was still molten. This introduced air bubbles into the base of the bowl. The stem was then pulled or 'drawn' and simultaneously twisted to form the spiral effect.
