Window Glass Analysis

Author(s): Grant Day

Year: 2014


Investigations by historical archaeologists reveal that window glass gradually increased in thickness throughout the nineteenth century. Numerous equations and methods have been derived for predicting an initial building construction date based on the thickness of window glass fragments recovered from a site. However, there are questions concerning the accuracy and application of these approaches, especially when dealing with sites that have a long period of occupation. By modifying and combining previous approaches it may be possible to conduct window glass dating analysis at sites that were considered less than perfect candidates. This approach may also provide information about the length of occupation, the building of additions or remodeling, and the use of scavenged materials.
