When a record consisted of more than one plate, the plates were strung together with a copper ring (or rings) passed through holes, and the ends of the ring (or rings) were secured by soldering with a lump of metal over which the seal was impressed. An intact seal was proof that no plate had been removed or tampered with. - [Previous: v1.c8.s2.5](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c8.s2.5) - [Next: v1.c8.s2.7](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c8.s2.7) - [Up: v1.c8.s2](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c8.s2) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v1.c8.s2.6](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c8.s2.6) · Pramāṇa
