Wistarburg Glass Works

The Wistarburg Glass Works (sometimes spelled Wistarburgh Glass Works; also known as the United Glass Company) was the first successful glass factory and joint-venture enterprise in the Thirteen Colonies. Caspar Wistar founded the glass works company in 1739. He began by recruiting experienced glass artisans from Europe, and built homes for the workers along with a mansion for the factory's foreman. Wistar also had a company store built near the factory.

The village that developed around the factory adopted Wistar's name, and became known as Wistarburg. The village was in Salem County, New Jersey, in the township of Alloway. Wistar's factory produced thousands of glass bottles per year, as well as window glass. Wistar was a friend of Benjamin Franklin, and made glass globes for Franklin's electricity-producing machines used for scientific research. Wistar's son inherited the business and his son, Wistar's grandson, eventually gained control of the company, but owing to his mismanagement it closed.
