Vasa Murrhina is the name of a glassware made by the Vasa Murrhina Art Glass Company of Sandwich, Massachusetts, about 1884. The glassware was transparent and was embedded with small pieces of colored glass and metallic flakes. The mica flakes were coated with silver, gold, copper, or nickel. Some of the pieces were cased. The same type of glass was made in England. Collectors often confuse Vasa Murrhina glass with aventurine, spatter, or spangle glass. There is uncertainty about what actually was made by the Vasa Murrhina factory. Vasa Murrhina means "vessel of gems." Related pieces may be listed under Spangle Glass.
