How do I clean my glass vessel?

Dust the surface gently with a soft, dry cloth to maintain the finish. Avoid using harsh chemical detergents or submerging mounted pieces in water. For internal cleaning, use lukewarm water and a mild soap solution without abrasive brushes. Dry thoroughly with a lint-free cloth to prevent water spots.

How can I tell Art Nouveau from Art Deco?

Art Nouveau pieces, produced around 1900, feature flowing, organic lines inspired by nature and plant forms. Surfaces often display iridescent sheens or cameo plant motifs. Art Deco items, dating towards the 1930s, favour strict geometry, symmetry, and stylised motifs. They frequently utilise clear, frosted, or deeply etched glass.

Are these vessels signed?

Many art glass vessels carry signatures, etchings, or moulded factory marks left by the maker or designer. These marks can appear on the base or along the lower edge of the body. Unsigned pieces still occur, identified instead by their distinctive forms, colour combinations, and manufacturing techniques characteristic of specific workshops.
