"Cobalt was used as a colourant in glasses, glazes, faience and enamels. Cobalt blue glass was first manufactured in the Bronze Age in imitation of lapis lazuli, a stone that was considered to have had health-giving properties (see Chapters 5 and 6). Much later, ground lapis lauli was used as an opacifier in enamel that was painted onto Islamic (Mamluk) glassware, including mosque lamps (as discussed her and in Chapter 10)." p. 69.

Henderson includes a great deal of information about glassmaking capabilities as well as social/cultural aspects. There are numerous references to previous studies of cobalt glass in Henderson's text.

Another useful new resource is:

Shortland, Andrew J. Lapis lazuli from the kiln: glass and glassmaking in the late Bronze Age. Leuven: Leuven University Press, 2012. 260 p.  "This book examines the history of the first glass, from its early sporadic occurrence, through the height of its production in the late second millennium BC, to its disappearance at the end of that millennium. It draws on an exceptionally wide range of sources including ancient texts detailing recipes and trade in glass, iconographic depictions in tombs and temples, archeological excavation of the most important sites [including Amarna and Qantir], and the description of the glass objects themselves. The area covered includes the heart of glassmaking and use in Egypt and the Near East, and to a lesser extent those areas were [sic] glass might have been traded, for example the Levant and the Mycenaean Aegean. It also considers the life of the glassmaker, his or her place in society and relationship to other industries"--P. [4] of cover. (Studies in archeological sciences; 2.)
