This study defined material and characteristics of 24 glass fragments and 26 whole glass beads. The feature of glass beads shape are divided into 5 types following color, size, weathering condition and manufacturing techniques. Through the chemical composition, the first and second type is soda glass, the third type is potash glass, the fourth and fifth type is lead barium glass. This site showed the aspect that the chemical composition is changed according to the feature of glass shape and was found that various chemical compositions. Looking at the flow of glass culture, the tomb that are lead barium glass IItype and potash glass I, IItype is relatively preceding period and the tomb that are soda glass and lead barium glass IIItype is following period.
