This is a lovely example of Moser Karslbad glass of a type made by them at the turn of the 20th century - this one is probably early 20th century as it is etched on the base Moser Karlsbad (most Moser glass is unmarked and they did not mark generally until later).
The colouration is a rich purple graduating to clear. The vase is hexagonal in shape, chamfered at the top and with a polished out pontil mark (which is etched as noted). The sides of the vase are deeply etched with two lilies.
The Ludwig Moser & Söhne glassworks was founded in 1857 in Karlsbad in Bohemia, Austria-Hungary (now Karlovy Vary, Czech Republic). In a short space of time they developed a worldwide reputation, winning many awards at major exhibitions such as the Paris and Chicago Expositions. They were particularly renowned for the techinque employed on this vase, known as Eckentiefgravur, employing a sharp angular body deeply cut in the form of flowers.
Height 19 cm (7.5 inches). Condition excellent - no faults, minor scratching to base.
