Vintage Fenton Art Glass French White Opalescent Hobnail Crimped Trumpet Vase, that measures approximately 7 1/2" tall x 7" trumpet with ruffled edge.  An absolutely beautiful piece!  Circa 1940s.

To make Hobnail pieces, the glass is blown or pressed into a mold. Hobnail, like Coin Dot, uses two different processes, depending on the colors. French Opalescent and milk glass are single layers of glass. Skillful cooling and re-warming brings out the opacity of the edges and the hobs. Crimped edges are made with the foot operated crimper.
