Pairpoint Manufacturing Company started in 1880 in New Bedford, Massachusetts. William L. Libbey established Pairpoint Manufacturing Company in New Bedford to make silver-plated metal mounts for Mt. Washington. It soon joined with the glassworks nearby and made glass, silver-plated pieces, and lamps. Reverse-painted glass shades and molded shades known as "puffies" were part of the production until the 1930s. The company reorganized and changed its name several times but is still working today. Items listed here are glass or glass and metal. Silver-plated pieces are listed under Silver Plate.
