The carafe is with a snapped pontil at the bottom from the glassmaker's rod, as well as a attached shoulder and neck, which indicates that from the 1850s.
The Kluk bottle is one of Holmegaard's oldest and best known pieces of glass.
It is made for almost the entire life of the glasswork in a wide range of colors and sizes, from the smallest of one deciliter to the larger of one liter.
They are made with crown stoppers for eg. The Viol series by Jacob E. Bang, collapsed variants for export and variants with nice painting.
This carafe is in the rare colored purple, violet, manganese color.
The real color is hard to capture on a picture, but picture three shows it best.
