Degenhart is the name used by collectors for the products of the Crystal Art Glass Company of Cambridge, Ohio. John and Elizabeth Degenhart started the glassworks in 1947. Quality paperweights and other glass objects were made. John died in 1964 and his wife took over management and production ideas. Over 145 colors of glass were made. In 1978, after the death of Mrs. Degenhart, the molds were sold. The D in a heart trademark was removed, so collectors can easily recognize the true Degenhart piece. All Degenhart glass is collected.
