Multi-Layer overlay are perhaps the most desirable of all Peking Glass bottles. They require much more expertise and are generally only made by the most experience artists. These can be two layers of overlay glass to as many as four or five layers. The quality of the carving and the thickness of the layer both play a part in determining the value. (the thinner the layers the better)

Carved Multi-layer overlay is perhaps the finest display of glass carving there is. The base glass is first carved in the shape of a flower or fruit, then multiple layers are added. Each layer is perfectly carved to expose only certain parts of the layer below.
