Polished
This is a mirror from an instrument used during the manufacture of semiconductors. The instrument measures the thickness of thin layers on the semiconductor. The mirror must be highly polished to give a good measurement. The rainbow colors are due to a film that built up on the mirror during its second career as a desk ornament.
