Container for Making Collyrium and Storing Vermillion.

This cast bronze container has three discs with shallow cavities for storing collyrium and vermillion. The discs are attached to a revette and are opened for use by sliding away one from another.
The top disc is held over the flame of an oil-lamp to collect soot in its cavity which is later turned into Collyrium by mixing ghee, camphor etc. into it. The middle disc probably had a mirror affixed to it.
