Changes in Indus Civilization bead materials over time

Stone and shell beads of Indus Civilization sites have been thoroughly studied and dated since the initial excavations from Harappa and Mohenjo-daro. However, the ways that materials used to make stone beads changed over time has not been as thoroughly examined. The goal of this research is to find chronological changes in materials used over time and better understand these shifts. This research will be collected from site reports and radiocarbon dates will be recalibrated with the Intcal20 calibration curve. Finding these material changes of bead making can give us a better insight to about the style or function of beads and what inspired them to make changes to a very old and important tradition such as bead making
