It consists of variable mixture of sand (20 to 40%) and gypsum (75 to 45%) or lime (2 to 25%). Lime mortar with a sizeable percentage of magnesium is also used at Harappa. It contains calcium carbonate (26 to 57%), magnesium carbonate (4 to 11%) and sand and clay (34 to 61%). The high percentage of sand and clay in lime plaster suggests that it was prepared by burning \*kankar\* (calcareous nodules). The use of lime was restricted to drains and floors. - [Previous: v1.c19.s6.8](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c19.s6.8) - [Next: v1.c19.s6.10](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c19.s6.10) - [Up: v1.c19.s6](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c19.s6) ## Linked texts (2) - [Harappā](https://indike.org/pramana/inp.site.harappa) - [Mohenjo-daro](https://indike.org/pramana/inp.site.mohenjo-daro) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v1.c19.s6.9](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c19.s6.9) · Pramāṇa
