Roman Window-Panes from Jerash, and Later Parallels
Published online by Cambridge University Press: 12 April 2016
Extract
It is not generally realized that the roller-moulded type of window-pane, so common in Italy and the western provinces of the Roman Empire from the first century A.D. onwards, was unknown, or at least extremely rare, in the East. Its place was taken, at least from the fourth century A.D. onwards, by circular panes of blown glass resembling very shallow dishes without a foot-ring. The rim is not plain, but is folded over outwards (a curious feature, presumably for added strength); the sides, normally about ½ to 1 mm. thick, are straight, and the bottom, usually 3 to 5 mm. thick, is bulbous, being flat or slightly concave externally. The average diameter is about 16 to 20 cm.

page 91 note 2 There is no proof that it was used at Karanis: only a few fragments occurred and these might have been used for glazing lanterns ( Harden, , Roman Glass from Karanis, 302 Google Scholar). The same holds good of fragments from Jerash. I am not aware of a single instance in the East where roller-moulded glass has a proved connexion with windows.
