Dorothy Thorpe Spiral Spring Umbrella lucite stand. This piece of early lucite sculptural art features a piece of lucite spun into a spring shape with a small holder along the bottom. All the qualities that made lucite a beguiling Material in the 1960s and 1970s—lightness, both visual and literal, a touch of glamour—remain true today. The California-born glass artist Dorothy Thorpe was something of a Pioneer in the use of lucite (the Material is, more accurately, acrylic; lucite is the trademark name coined by DuPont), experimenting with the stuff as far back as 1941. Unlike her midcentury contemporaries, Thorpe exchanged hard-edged geometry for freeform, amorphous compositions: knotted, twisted, spiraling tubing that, even today, looks technologically advanced. Much of Thorpe’s earlier glasswork was characterized by Art Nouveau–influenced floral motifs. But by the 1970s, and evidenced by these graceful pieces, she smartly traded in bells and whistles for pure, sculptural elegance. In good original condition, it retains its plastic bottom and measures 11 X 23″h. $295.
