As for mirrors, it was in Venice during the sixteenth century that the process of coating flat plates of glass with thin coatings of reflective metal, usually a mixture of tin and mercury, was developed and closely guarded. The process was extremely time consuming and dangerous for the craftsmen; hence, mirrors were very expensive items. They were housed in frames carved of ivory, wood, or precious metal that were works of art in themselves. Here, for example, is a photograph of a sixteenth century carved walnut mirror frame.
I'll leave you with a painting that is purported to be of Diane de Poitiers, Henri II's mistress, regarding herself in a mirror. The painting dates from about 1590, so if it is of Diane, she's looking pretty good for being all of 109 years old! A jeweled mirror perched on a sculpted base stands to her right.
