Abstract: When was the earliest glass produced in China? This has still been a question so far. Some archaeologists have thought that Yu Guo beads are real glass, the earliest glass(1100～771 B. C.) in China. However, more details of scientific investigations in this paper show that Yu Guo beads are mainly made of clastic quartz (>95%) with a small amount of clay and sintered under the low temperature(500～600℃). It is not a glassy body, but a kind of polycrystal ornaments.

Key words: Ancient beads, Physico-chemical characterization, Polycrystal ornaments
