Glass Exchange and Changing Networks at Phromthin Tai, Central Thailand
Year: 2026
Type: article
Abstract: This study examines glass beads from Unit S4 at Phromthin Tai (PTT), Lopburi, to investigate changing exchange networks during the transition from the early to later first millennium ce. LA-ICP-MS analysis shows that the assemblage is dominated by m-Na-Al 1 glass associated with southeastern India, while m-K glass, linked to South China Sea-oriented networks, occurs only in a few earlier contexts. Comparison with the previously published S3 assemblage reveals a marked shift from m-K glass toward South Asian m-Na-Al glass within the Mekong Interaction Sphere. The identification of v-Na-Ca glass further expands the compositional diversity of the PTT assemblage.
