A rare hand carved Chinese peking glass square box. Chinese Overlay Carved Glass, also known as Peking Glass, is a traditional form of art that starts with a one-color glass base, dipped into contrasting colored glass one layer at a time. The artist then carves away portions of the overlaid glass to reveal layers of other colors underneath. It is a lengthy and tedious process that is time consuming and labor intensive. In the old days, glass is very easy to break and very hard to carve. A square box of Peking glass was rare. The size of the box is about 4.5" square. It is in very good condition.
