This is just a little logo sample of what an engraved glass mirror looks like. It’s actually the back foil that is engraved- if it was the glass on the front you would see a double image/ghosting effect.
When glass is engraved it takes on a textured/whitish appearance. If it’s backlit, the engraved part is translucent enough to see colour behind it… I keep thinking this would be interesting to put a light box behind, or even hang it in a window as part of a stained glass installation.
It’s also not the easiest thing to photograph!
