Chemical Composition: XRF data from Artax 1
Alloy: Leaded Bronze
Alloying Elements: copper, tin, lead
Other Elements: zinc, iron
Comments: There is zinc-rich solder on 1969.177.20.B. The mirror discs have the same elements.

Technical Observations: The patina of both mirror components is very corroded and has green, red, brown, and orange encrustations. The surfaces are poorly preserved. The edges of both components are damaged with gouges and lead solder as the result of a modern repair attempt.
The discs were cast. It is possible that the turn lines, visible on the interior of 1969.177.20.A (the mirror) and on the exterior and interior of 1969.177.20.B (the cover), were done by the engraving and removal of the metal surface, but it is also possible that these lines were created in the wax model given the amount of metal that would have been removed. Although the surfaces are poorly preserved, the pattern of rings is very similar between the interior of 1969.177.20.A and exterior of 1969.177.20.B. The exterior of 1969.177.20.A was plated with a white metal. Its outer rim was made from a separate piece of metal that was probably formed by hammering and attached with a solder that has corroded and is now not apparent.
