The best for this is:

- Make a bronze glass material (I should post some official ones soon, but you can tweak it easily)
- Make a smooth silver material : a non-transparent specular material with a refractive index between 50 and 100 (which gives a reflection coefficient between 98% and 99%, which corresponds to silver). You can also make a phong with Ag.nk and a high exponent, but this will not be perfectly specular)

Model your mirror with its real thickness (such as a 4mm thick cube). Apply the silver material to the backface and the bronze glass material to the other faces.

This will be the most physically realistic way to model your mirror, with nice real trench and angular variation color effects.

Sorry Galinette, but applying the specular mat to 5 faces of the box instead of 6 (because the back face is painted with the silver mat) won't cause the result to be non realistic?

Nope, it will be physically realistic

As soon as:
- The medium are the same
OR
- One material is not transparent (checkbox set to false)

Mixing specular materials on a single shape does provide correct results.

Result is perfect
