Characteristics of Plymouth and Bristol Porcelain.
Among special features of Plymouth and Bristol china, spiral ridges are to be seen, though often barely noticeable, running from the base transversely around the body of piece, more noticeable in basins and teapots, at an angle of 45°. The china of these factories is often untrue owing to imperfect firing, and is frequently cracked at base. The Bristol decorators had a partiality for wreaths and festoons of laurel in green, interspersed with detached bouquets of flowers. The Bristol glaze is rich and creamy white, and upon examination a series of minute depressions, somewhat similar to the bubbles on Oriental glaze, may be discovered.
