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.

I’m sure there are varying methods, but typically you silver the back of glass to make a mirror
I think you are right. I keep finding different ways they did it, so sounds like the 1800s was a busy period in the development of mirror technology!
Huh, so 7 years bad luck was actually just heavy metal poisoning? Fascinating…
