    As I recall, the “Vampires have no reflection” stemmed from mirrors of the time usually being polished silver. So, I guess the vampire can do this if they’re okay with having silver pressed up against their face.

      How does that guy with smoke coming out of his eye patch always know when I’m sneaking up on him?? At night. While he’s screaming.

        Pretty sure they just poured silver nitrate over glass. You can still buy kits to do that to re-silver old mirrors for the original look. From what I can find, the layered ones were older, and they used tin and mercury which made breaking a mirror a rather unlucky event.

      Mirrors now are chemically deposited silver to my knowledge.
      Deposited on the back of the glass, then a protective layer applied on top. The amount of silver in that assembly is very low, and none is exposed, but the reflective component is the silver.

          I’m not certain, can’t find any reliable info on this.
          Shops don’t seem to specify the reflective material. In addition, aluminium is commonly used to describe the frame, and silver as a color for the frame or other parts, making it hard to get any info on the sales side.

          On the production-tech side, I see some pages talk only about silver, others mention both silver and aluminium. Silver commonly has a description of the chemical process at times (silver nitrate silvering), haven’t seen one for aluminium yet.

          Price wise, metal should be fully opaque around 10nm. Assuming a generous 100nm thickness, that makes 0.1€/m² worth of silver. I doubt material cost is a factor.

          Performance wise, silver seems better than aluminium in its reflectance. Honestly I don’t get why anyone would be making aluminium mirrors.

          Does anyone have more info on this?
