Usually it is just referred to as mirrored, they use it for thermal insulation along with a vacuum, or to protect photo chemical sensitive
reagents/reactions.

The silver is usually on the inside of the vessel, but in dewars, they are double walled, so the silver in normally on the inside of the vacuum part,
thus not toughing the inside space or the outside of the item. That protects the silver from abrasion and oxidation.
The silver is put there normally to reflect infared radation (heat), just like in a thermos bottle, you want the heat (or cold) conditions to stay
inside the bottle. There are other uses like protecting chemicals from light, but that can be done other ways as well. It is also handy for
seeing your self in the glassware, like in a mirror.

The first just looks like old Chinese glass that is dirty, or a poor silvering. Not sure what that is.
Second one is red/amber glass for working with photosensitive compounds.

Huh I found a silver coated glass jug from several decades ago (50s - 70s) and it looks pretty normal, with a red plastic shell on the outside,
making it look like a normal coffee pot. Makes me wonder how many could be sitting around in thrift stores/ etc. (It was used as a coffee pot when I
found it, it was being thrown out. It had migrated to a kitchen from a university lab somehow.)
