Chemical compositions and lead isotope ratios for four glass bead samples of Seokga-tap were analyzed and the results were organized. Among 4 glass beads found in the Seokga-tap, 3 pieces were lead glass. Manufacturing method was to firstly grind pebbles finely and mix lead ore to be melt at 740～760℃. The mixed ratio of silica and lead was 3:7. Moreover, The evaluation on the lead isotope ratio indicated that two lead glass pieces used lead ore from northern Korea.
One piece has the direction of southern Korea lead ore, but it requires a further review. One glass bead of Seokga-tap was brown and it was potash lead glass (K2O-PbO-SiO2) System. The mixed ratio was approximately 50:10:40 for silica, natural saltpeter, and lead, respectively.
Lead isotope ratio data fell within the lead ore from northern China.
Therefore, it was concluded that potash lead glass found in the Seokga-tap was produced in northern area of China at the end of 10th century and transferred to the Seokga-tap.
