This has been discussed before.
Insert wood shims between mirror and wall, all around. This applies outward
pressure. Pour solvent (like "Goof Off") down back side of mirror to soften
adhesive. Wait. More shims as mirror separates from wall. etc. etc.
You can thank me later.

Wish to remove a large cracked mirror glued to a bathroom wall.
Thought is to duck tape it and then try to break it but wonder if there
is a dremel tool for cutting glass that would be better to use?

Any suggestions.

Thanks
