Georgian composite stem wine glasses combine two stem forms one "set in" (above) the other with a knop or collar at the point where the two stem types are adjoined. Thus a single series air twist section set in a baluster stem becomes a possibility - and a beautiful one at that ! Composite stems frequently have an air or opaque twist section in combination with a plain stem section, the plain stem section possibly having air tears beaded knops.
Composite stems on 18th century baluster glasses are both elegant and tactle and thus very usable, particularly when the glass has a good-sized bowl. There are some wine glasses with composite stems comprised of both plain and facet cut sections, these are predominantly late 18th or 19th century. Twist stem sections combined with Georgian cut glass stems is a rare combination on Georgian wine glasses. This is rarely seen on on some Georgian drinking glasses.
