A gaffer at Kensington Glassworks added legs, a dorsal ridge, and a tail to transform this common flask into a beguiling turtle. It was intended to be a whimsy and most likely never served a functional purpose. The back of the turtle depicts a sailing ship, and the phrase "Free Trade and Sailors Rights," a popular political slogan during the War of 1812, runs around the edge. The mold for this flask was made in support of the war, but this turtle was undoubtedly made later. Metal glassmaking molds were costly to produce, and manufacturers reused them as long as they could, sometimes selling outdated molds to other glasshouses. With its vivid, emerald green glass and intact legs and tail, this turtle whimsy is a rare survival.
