Splashed glass is thought to have been created in imitation of mosaic glass. The process of marvering and further inflating picked up glass on blown vessels was produced in both eastern and western glass centers from 20-70 A.D., with a peak of production around 50 A.D. (see p. 207ff. and nos. 361-362 in Whitehouse, Roman Glass in the Corning Museum of Glass, vol. I, and nos. 109-110 in Matheson, Ancient Glass in the Yale University Art Gallery). For a similar example see no. 185 in Kunina, Ancient Glass in the Hermitage Collection.
