DescriptionThis free-blown and tooled glass vessel consists of a spherical body with an interior diaphragm. The glass is transparent manganese-colored very dark red (near 5 R 2/6) with possibly opaque white thread. The vessel is made of medium thin glass. The fabric cannot be determined because of weathering. The pontil mark is approximately 1.8 cm in diameter. The rim is outsplayed at a 45-degree angle and folded outward, upward, and inward. The neck is slightly tapering and tubular with a constriction at its base, where an interior cutout forms a diaphragm with an aperture of about 1.1 cm. The spherical body ends in a round base; the vessel cannot stand on its own. Around the body are approximately sixteen revolutions of thread. The thread decoration was added after the body was formed.
