During the Roman period, glass window panes could be made by two processes: they may be cast, or blown by the cylinder‐blown method. The thermal history and the fictive temperatures ( T f ) of both sides of the pane are different depending on the process employed. The wavenumber of some Raman peaks depends on the fictive temperature of the studied sample. Calibration curves are drawn with some annealed samples, which are used to determine the fictive temperature of the window glass sides. This method is applied with success to different archaeological panes to obtain their thermal history and, by this way, their manufacturing process. Copyright © 2008 John Wiley & Sons, Ltd.
