Pendulum glasses were mainly blown in the 2nd half of the 18th century.
A rich variety of spiral types were used, especially in the United Kingdom.
There the spirals were inserted into lead glass, glass that had great clarity due to the addition of lead oxide.
In the Netherlands, the spirals were inserted into soda glass, a type of glass that is less clear and shiny.
In the Netherlands, the variation in spiral types is also more limited and usually consists of a sleeve with many thin spirals around it.
Due to the difference in glass type and spiral, the origin of the glasses can also be determined with reasonable certainty.
This sling glass comes from England and was made around 1860-1880
Decorated with beautiful wild engravings, the glass gives an extra status feeling.
truly a collector's piece
