The back of the mirror attached to the wall is glued with white glass, and there may be foam double-sided tape in the middle. Because the viscosity of glass glue is very high, the viscosity can only be reduced by lowering the temperature, so before disassembling the mirror, the front of the mirror should be treated with ice cubes at low temperature.

Then cut off the glue on both sides, first down and then up. It is best to send someone to hold the mirror steady during the operation to prevent the mirror from suddenly falling down and causing an accident.

If all four corners are glued, use a saw to separate the glass glue from the four corners.
