Chemical analysis of 31 glass beads from the sites of Mahilaka and Sandrakatsy in Madagascar, which date to approximately the 9th to 15th centuries CE, reveals the presence of two main types of glass: mineral- soda glasses and plant-ash glasses. Most of these glasses were probably made in South Asia.
