The National Heisey Glass Museum Collections consist of more than just glass items. The Museum houses over 4000 moulds in a warehouse specially purchased by Heisey Collectors of America, Inc. members. These moulds were used to produce the elegant glassware by A. H. Heisey & Company between 1896 and 1957. Members of HCA realized that the moulds and related materials, including etching plates and production records, constituted a priceless heritage that needed to be preserved to enrich our knowledge of Heisey glass and prevent deceptive reproductions from harming the Heisey collecting experience.
