Repair Reflective Surface of Large Mirror


(2001)

I have a large mirror and some of the rhodium is missing. How can I repair/replace the reflective surface?

You have to re-silver the mirror. Take ALL precautions!

Wait a minute there folks ...

When you say "large mirror and some of the rhodium is missing", you are implying that this is a front surface telescope mirror. If so, this is absolutely not a do-it-yourself project.

But if you simply mean a large home mirror, the problem is that you used the word "rhodium", which has nothing to do with a conventional mirror. The coating is just silver, on the back surface of the glass. Rhodium is not required to keep the silver from tarnishing because the glass keeps the air away. Good luck.
