Most American paperweights with enclosed flowers were made by glassblowers on their own time, using leftover glass. One of the most skillful of these makers was Ralph Barber of Vineland, New Jersey, who created the type of open red rose that is featured in a mantel ornament made in the early 1900s. The rose was formed by applying a pad of red glass to the side of a colorless glass sphere. The glassmaker forced the hot red glass inside the colorless ball with a “crimp” whose curved metal fins were arranged in concentric rings on a wooden handle. As the ball was reshaped, rounded, and covered with another layer of colorless glass, the back of the rose was rounded and closed. A lampworked green stem and leaves completed the decoration.
