This is a lamp with a blown shade and pressed, triple-dolphin base. Dolphins were a very popular decorative motif in the neo-classical period and are found as furniture supports, and in a variety of glass and metal lighting fixtures. The pressed triple dolphin also was sometimes used as a support for compotes. This example, the only one found so far in blue, is fitted with a handsome brass collar with an embossed grape design in relief. The original colorless shade is decorated with a matching cut-grape design. It was made by the Boston & Sandwich Glass Company, in Sandwich, Massachusetts, the only glasshouse known to have produced these bases. Although these are usually referred to as lamps, they are candle fittings with shades. Candlesticks with shades are not common in American glass, because, in the north, windows usually were not open, and therefore the flame didn’t need protection from air currents. The shades were more ornamental than useful.
