My father is attempting to remove the mirror from a piece of glass. We stripped the black paint from the back and exposed the shiny surface with acetone. In the past he has been able to remove aluminum mirror with lye, but that didn't react. We also attempted bleach in case it was actually silver but that didn't react either. Is there another metal that could be used to back a mirror? Are we doing anything wrong? Also adding hydrogen peroxide to the lye made the mirror bubble but no black silver oxide or white aluminum oxide.

  • $\begingroup$ I'm not sure if this will help, but en.wikipedia.org/wiki/Mirror#Types_of_glass_mirrors has several other types of glass mirrors in addition to aluminum and silver backed mirrors. $\endgroup$ – JSCoder says Reinstate Monica Feb 11 '18 at 23:43
  • $\begingroup$ Try to use HNO3 on it... Or maybe there is still a thin plastic coating over the metal that was resistant to the acetone... $\endgroup$ – Andreas Nov 27 '19 at 13:14
