Through constant experimentation, Murano’s glass guild evolved a series of innovative techniques such as sommerso. The method requires an authentic knowledge of colour combinations, as well as a high level of dexterity in blowing and layering. To achieve the beautiful results of pieces such as this Salviati ashtray, articles are submerged in clear molten glass of a different colour, producing a layered, chromatic effect. Please note, this item is a truly original vintage piece with slight imperfections and distinctive characteristics that add to its charm and celebrate its unique history.
