A type of glass manufactured by German-American John Frederick Amelung’s New Bremen Glass Manufactory in Maryland, U.S. between 1784 and ca. 1795. Amelung brought over German craftsmen and sought financial support from German and American businessmen and the U.S. government in establishing a permanent crafts community. His industry failed after the U.S. Congress rejected Amelung’s request for a loan in 1790. Our understanding of the technique and style of this glass is largely speculative and fragmentary as few examples survive.
