The Chinese were fascinated by using materials of one sort to imitate another. It is a high compliment to the craftsman, and considered an clever device, to use less expensive materials to imitate something rare or precious. Thus we have a rather excellent example of Peking glass, or twisted glass, imitating snow white and apple jadeite. Just the right balance of the apple green glass is included to rise to the surface of the white batch, and then the bottle is carved and polished to produce the end result you see. The bottle is of rounded, flattened form, standing on a carved footrim, with a concave mouth. Of course, being glass it is extremely well and deeply hollowed. The top is a later addition, as we purchased this one minus a top, as many antiques are found. We paired a well made tiger eye cabochon top, with good chatoyance, that features a brass color and hammered brass spoon. Rubber and thread stopper. The bottle itself measures 2.36 inches tall, or 6 cm. With the stopper in place the total height is 2.87 inches, or 7.3 cm. Bottle is free of any condition issues. Part of a private estate collection, which featured many bottles acquired from Sotheby's.
