The New England Glassworks was a short-lived glass-making factory located in Temple, New Hampshire in the 1780s, and one of the first glassworks in the United States. Founded in 1780 by Robert Hewes, a Boston-based businessman, the glassworks employed Hessian deserters from the British forces of the American Revolutionary War. The glassworks was established in 1780 and failed due to a lack of financing in 1783. Its abandoned site was excavated in the 1970s, and is now listed on the National Register of Historic Places.
