    To tell if a bird sculpture is made of Murano glass, professionals recommend having an antiques dealer or Murano glass expert examine it. Otherwise, look for the signature of the artist or factory on the piece. Authentic Murano glass will often, but not always, include labels with the name of the workshop, the signature of the glass master and a certificate of authenticity. Use trusted online resources to determine if the maker's location is or was in Murano, in northeastern Italy. Seeing the word "Murano" on a glass decorative object doesn't mean that it is authentic. In fact, most genuine pieces won't show the word "Murano." Murano glass is identifiable by its richly layered colors and characteristic gold or silver flecks inside the glass. Authentic Murano glass often has small imperfections and an irregular shape due to the freeform creation process. Find a collection of Murano glass decorative objects on 1stDibs.
