Glass and Mirrors - Broken Mirror--Any way to cover it?

We have a HUGE framed mirror bought at a furniture store (75 inches by 45 inches).

We were trying to hang it tonight and got a 5 inch crack in the bottom corner of the mirror.

I know there is no way to fix the crack, but I'm hopeful for a way to salvage the mirror. Do you have any recommendations about frosting or painting the mirror to cover the crack. The crack is on the outer edge of the mirror, so I was wondering if we could somehow fill the crack and then paint a black trim around the outside edge of the mirror to cover the crack. But we have no idea if that will really work.

We have another really large mirror (former double bathroom vanity mirror) that we could try to use to replace it. But I'm worried that by the time we take apart the current frame, mirror and thick glued cardboard backing and re-cut and replace the mirror, the cost will start to become more than the original mirror.

Any comments or thoughts would be greatly appreciated!

Thanks,
Hannah

If the crack starts in the corner and goes out 5", chances are that the crack will continue to run in the direction of the crack. If this is the case, don't bother. If the crack goes from the edge of the mirror and ends at the other edge (like an arc) then you're OK to hide it. You can buy 6" beveled strips at HD or Lowes, cut them to size and glue them around the perimeter of the mirror.

The crack was in an arc shape, so we were able to save the mirror. The frame was very curved, so we couldn't use bevel strips. We tried frosting it first, but that didn't cover the crack. So we painted a 4 inch peremiter of metallic paint, which covered the crack. Not ideal, but good enough to put it up on the wall.

I appreciate your advice!
