Can this glass be salvaged?

  • I’ve been wanting to build a magic mirror for a while and was lucky enough to be given a piece of 2-way glass, but my excitement faded when I tested it in front of a monitor and found it’s quite dark and not particularly reflective. It looks like what you see when you look at a car window that has a dark tint.

    In the shot below I set a handheld mirror next to the 2 way glass to illustrate the difference.

    My question is, is this just due the inherent properties of the glass or will it be improved when I black out the area behind the glass? Or is there any other treatment or polishing that would improve reflectiveness?

    Thanks in advance for any suggestions…

    Throw something dark behind it and see what happens.

    It looks like there’s not a lot of reflectiveness to that mirror. You’re not going to improve on that. On the plus side, it means that whatever is behind that glass will show through really well. 🙂

    I think you can salvage it, but you’ll probably want to put the mirror in a bright area. The transmission through the glass should be very good, so you’ll be able to see the content even in a brightly lit room.

  • @bhepler Thanks for the feedback. For this first project I do need something quite a bit more reflective so I think I’ll continue the conversation with the glass shop to see what else they can source.
