This presentation provides a summary of development of glass bottles and other containers in the late historical period (ca. 1865–1972). Glass bottles and metal cans are arguably the most common artifact types identified on archaeological sites in Arizona. Formerly known as the “Baby State,” Arizona’s rural and urban landscapes took shape following the American Civil War. A number of communities in Arizona produced glass containers for distribution across the territory. With the completion of transcontinental railroads and connecting branch lines after 1880, bottles and glass containers were shipped from hundreds of factories across the country. This webinar will focus on providing information for dating “utilitarian” bottles and other containers through the recognition of specific bottle attributes and locating manufacturer marks and other diagnostic marks.

A zoom link will be sent the day before the presentation to those who register. If you register and do not receive a link, be sure to check for the notification in your spam folder. The presentation will be recorded, and the recording will be posted.
