Community Programs & Events

FREE and open to the public; no advanced registration required. Would you like to see the artifacts and talk with archaeologists who are working on the I-95/Girard Avenue Project? Throughout the year we hold a variety of free public events. We display artifacts, explain how we found them, and discuss how these objects were used


We engage in a number of activities to tell others about the project. At our free community events the public can see the artifacts and talk with archaeologists. We partner with local museums to provide engaging educational exhibitions and programs. Professional colleagues may learn about our current research at professional conferences. Occasionally we can provide

Free-Blown Glass

Free-blown glass is formed without the use of molds. The glassblower inflates the glass on the blowpipe and manipulates it with tools to make the desired form, such as a bowl, pitcher, or drinking glass.   In a traditional glasshouse setting, the head glassblower of each team or “shop” is called the gaffer. To make


Local Glass History Between the 1770s and 1920s, at least seven glass factories were situated in or near the I-95/Girard Avenue Project area.

As you will see, different types of records were kept over time—some still available, while others have been lost. Though records

Mold-Blown Glass

Glass may be blown, either by mouth or machine, into a wood, clay, or metal mold to give it form, decoration, or both. Using molds enables quick, uniform reproduction of specific shapes, sizes, and designs. Dip Molds The simplest molds are one-piece dip molds. The glassblower lowers the gather of glass into the mold, inflates

Museum Exhibitions & Programs

Pressed Glass

The concept of forcing glass into a mold to give it shape is an ancient idea, but tools specifically designed for this purpose developed gradually in the 18th and 19th centuries. Plier Press From about 1740 to 1900, a two-handled tool, sometimes called a plier press, was used to pinch glass chandelier drops, small stoppers,
