Thread: What reaction of silver deposits on solid surfaces quickly?

I've seen silver nitrate mixed with a clear liquid, some kind of copper solution I've been told, that will create a silver film that adheres to the surface of the container, and solidifies onto it.
Does anyone know what reaction that is?
Thanks.

This sounds more like diaminosilver(i) or the Tollens' reagent. The solution is readily prepared from silver nitrate and concentrated ammonia. When reacted with a solution containing an aldehyde (such as reducing sugars like glucose) the silver is reduced to the metal which deposits on the container wall. If done on glass it creates a "mirror" like surface.

This reagent is unstable on prolonged standing and is neutralised with nitric acid to prevent explosions.
