Russco is a popular Art Deco pattern introduced by Roseville Pottery in 1934. Standard colors include blue, gold, green, and salmon. The blue and salmon examples have matte glazes. Both the green and yellow glazes have a crystalline quality, and some green examples have crystals large enough to resemble snowflakes. These highly crystalline examples bring higher prices than the matte glaze examples. Russco was marked with foil labels, and some examples have hand-written shape numbers. The factory stock pages show 24 shaped for the Russco pattern, including vases, bowls, candlesticks, cornucopias, and flower blocks.
