'Murano' is used loosely in lighting, and not every piece sold under the word was made on the island. This page is deliberately short. A piece appears here only where its maker states in its own specification that the glass is Murano glass, and Caspen does not use the word on the strength of a family resemblance.
If provenance matters to the purchase, ask to have it in writing, naming the furnace if the maker will. Our piece on naming the furnace sets out what to ask. The Murano Glass Mark is a separate certification, and it is the maker who can tell you whether a piece carries it.
