In 1860, Franz Bergman founded a small bronze foundry in Vienna where he produced many patinated "cold-painted" bronzes. The technique of cold-painting bronze derives its name from the use of layers of unfired "dust paint," otherwise known as poly-chrome paint, which is applied directly to the metal surface after casting. This method results in vibrantly colored bronze patinas that were often used to decorate exotically themed sculptures or animal figures. Our unmarked easel-back picture frame with its grape and leaf motif and Arts and Crafts palette is probably American from the last half of the 19th century. Originally, it may have been part of a desk set; such sets often included weighted writing services, inkwells, letter openers, calendar frames and thermometers. The technique of using dust paint was primarily a cottage industry that has been all but lost. Condition: Excellent, new glass and backing. Dimensions: 8.5" x 5.25".
