optical effect
It appears broken because of the reflection of the object and it's from the other molecules hitting the water which causes a bend like appearance to happen the light bends.the light bending is called refraction.
It will crack because like clay in a hot oven, if all the spots are not covered correctly, it will have a chance of cracking, but when the hot water gets into the crack, it will start to make it bigger. If the expansion is uneven, the glass will break and I don't understand why it won't break with a metal spoon.
There is no spoon, so the question is meaningless.

Any reaction occur.
An absinthe spoon is used to sweeten the absinthe. The spoon is placed on the rim of a glass and a sugar cube is placed in it. Ice cold water is dripped onto the ice cube and into the glass.

use for pilsner glass
nothing will happen as copper is more reactive than silver.
as silver is less reactive than copper the silver when immersed will loose its electrons and the copper will displace it. i apologize if it is the wrong answer.... this is actually a guess :P

As the metal spoon is a good conductor of heat and because heat travels from a hotter reigion to a colder reigion,the metal spoon will conduct heat away from the hot water and thus,the emty glass will not crack.
If we pour hot tea in glass tumbler the tumbler will expand and break off. So to prevent it we keep a metal spoon in it,as it is a conductor of heat it will absorb heat and prevents the glass from breaking.
You don't.
