Lapis lazuli was probably obtained at a later date from contact with the Harappan folk who acquired this substance mostly from Persia and Afghanistan. Beads made of a glass frit, very similar to faience, found in the cemetery must also be of later date, indicating contact with the Harappan people. The finding of a perforated stone weight very similar in shape to those from Mohenjo-daro confirms this view. - [Previous: c10.12](https://indike.org/pramana/ins.science.ray-1956.c10.12) - [Next: c10.14](https://indike.org/pramana/ins.science.ray-1956.c10.14) - [Up: c10](https://indike.org/pramana/ins.science.ray-1956.c10) ## Linked texts (1) - [Mohenjo-daro](https://indike.org/pramana/inp.site.mohenjo-daro) --- Source: [https://indike.org/pramana/ins.science.ray-1956.c10.13](https://indike.org/pramana/ins.science.ray-1956.c10.13) · Pramāṇa
