The surface of this bowl shows that the term ” mosaic glass” is an appropriate one for designating the type of glass they are made of. The earliest examples of objects made with this technique date to the middle of the second millennium BC. Mosaic glass is obtained by making a bundle of different-colored glass canes and slicing it widthwise into little rounds. These are set one beside the other in a mould that is then placed in a kiln. This glass molding technique continued to be used until the first century of our era but was eventually supplanted by glassblowing. Glass receptacles were not used as everyday objects until that time.
