Posted on January 25, 2019February 18, 2019Roseville Experimentals Gallery The backside (with incised instructions for coloring) of the Arrowhead experimental (left) and the smaller Firethorn experimental. Neither line was put into production. Coffeepot from the Mock Orange line, first produced in 1950, typical of Roseville’s late production style. Two valuable Roseville vases from the 1920s which had paper stickers, and which may appear today with no mark. The smaller is from the Futura line and the larger is from the Imperial II line. The Wisteria line, produced in the 1930s, is highly valuable today. This 12 inch blue model could sell for $2,000 or more in mint condition. An elegant, carved Della Robbia teapot, ca. 1906. Some collectors consider Della Robbia to be Roseville’s greatest line. The backside (with incised instructions for coloring) of the Freesia experimental (left) and the smaller Firethorn experimental. The latter was purchased at a Wisconsin flea market for $35 a few years ago, and its Baneda style glaze hints at a 1930s origin. The Freesia line was produced by Roseville in 1945; the Firethorn line was never produced A “400 series” Pine Cone bud vase designed late in Roseville’s history on the left, and an older model bud vase, designed in the 1930s, but also in production in the early 1950s with a new “400 series” number. A sleek Pine Cone “400 series” ewer from the late 1940s or early 1950s, and the smaller, older model designed in the 1930s. The Blackberry experimental. The Blackberry experimental.
