Insulators & Ammunition

February 17, 2022

View the recording on the Arizona Preservation YouTube channel

This presentation provides a summary of development of glass and ceramic insulators, as well as ammunition in the late historical period (ca. 1865–1972). These artifact types are quite common on archaeological sites and other historical resources in Arizona (i.e., buildings, structures, and objects).


Formerly known as the “Baby State,” Arizona’s rural and urban landscapes took shape in this period. Insulators were essential components of early telegraph lines, especially in the peak period of railroad development. With the success of telephone service and electrical power through the course of the twentieth century, insulators were manufactured in a variety of styles, reflecting their function and on a variety of utility and transmission lines.


Although archaeologists rarely find evidence of firearms on archaeological surveys, spent cartridges and shotshells are much more commonly documented. The challenge for archaeologists is to determine if ammunition documented on sites is affiliated with the site or with later hunting or recreational activities.
