The mixed alkali glass beads are all opaque red mutisalah beads with a high copper content, probably of Indian manufacture. The potash glasses include all colours and degrees of opacity and it is now generally thought that some were made locally in Southeast Asia, even at this early date, since they include forms never found in India. Khuan Lukpad, Tha Muang (U-Thong) and Oc Eo were glass bead manufacturing sites during the early centuries AD, but they have been much disturbed by
bead diggers. There is as yet no unequivocal evidence to date the manufacture of raw glass back to the prehistoric period in Southeast Asia, although raw glass cullet may have been imported earlier than this and worked into beads and other ornaments.
