being a poor radiator,the two silver faces reflects heat back and forth and reduce heat by radiation.
The mirror substrate has either a polished silver or aluminum coating to the back .
The flask has a double wall, with no air between the two walls (vacuum)- conduction. The walls are highly reflective silver- radiation. the flask has a small beck that is closed by a stopper or cap-convection.
A mirror.
Using vacuum as an insulator avoids heat loss by conduction. Heat transfer is minimised by reflective silver surfaces that are applied to the flask. This prevents thermal radiation from entering and escaping the flask.

Tin chloride coating to sensitize silver deposits ,silver nitrate for silver coating and copper paint for protection to the silver deposits.
It is silver oxides (Ag2O) or the rust of silver.

Floride
They are highly reflective.
The coating on the back of glass that makes it into a mirror used to be silver. Now it is usually aluminum.
because of sulphide coating on silver

no.
Avon rings do not contain silver in amounts measurable in percentages.Usually they have a silver coating, however any silver content in that will not be of importance.
With a silvery coating on it, it has now become a novelty item with no collector value.
