At the bottom it is closely packed with cow-dung cakes up to a height of 20 to 30 cm. The sealed jar is placed at the centre of the pit above the cow-dung cakes. It is then fully surrounded with cow-dung cakes and excess cakes are piled up above the pit. It is then set fire to and allowed to burn first slowly for a few hours, and then with strong intense fire for 8 to 12 hours. Within the jar the pottery is baked in a reducing atmosphere of excess carbon monoxide. Under the reducing condition the pottery develops a black surface finish. - [Previous: v1.c21.s12.7](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s12.7) - [Next: v1.c21.s12.9](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s12.9) - [Up: v1.c21.s12](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s12) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s12.8](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s12.8) · Pramāṇa
