A vibrant and tactile example of American art glass featuring the iconic raised hobnail pattern in a deep emerald green hue, expertly crafted with a characteristic crimped and ruffled edge that lends a delicate, undulating silhouette to the weighted form; the glass contains a small amount of uranium, allowing the piece to emit a luminous green glow when viewed under ultraviolet light, making it a prized specimen for collectors of mid-century glass and fluorescent minerals; measures approximately 4 1/2" H x 10" in diameter; good condition.
