The specimens represent soda-lime-silicate glass and are characterized by a high proportion of lime and magnesia and a low content of the sesquioxides. The presence of lead (PbO) in AC2 is significant as the use of lead in glass-making in the 1st century is very rare. The blue colour is due to copper oxide and the green to the combined effect of copper and lead oxides. - [Previous: v1.c21.s8.7](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s8.7) - [Next: v1.c21.s8.9](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s8.9) - [Up: v1.c21.s8](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s8) ## Linked texts (1) - [Ahicchatra](https://indike.org/pramana/inp.site.ahichchhatra) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s8.8](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c21.s8.8) · Pramāṇa
