Copper sulfate is formed.

Hot copper wire gives off no fumes.However if you are talking about insulated copper wire, the insulation will give off fumes. Depending on the type of insulation it can be anywhere from totally safe to deadly!
If the copper wire really is pure copper then the only element in the copper wire is copper (Cu).
Copper wire sent for recycling is remelted and rerefined. It becomes a new copper product one of which might be new copper wire.

The copper wire glows red. Once it cools...the copper reacts with the air to produce copper(II) oxide. This is shown by the black tarnish on the copper wire.
Copper Sulfide
It depends on what you added to the methanol before you put the heated copper wire into the methanol. The heated copper wire acted as a catalyst to speed up the reaction between the methanol and the other substance. Copper itself does not react with methanol.
The matter in copper wire melts then explodes into a green flame
copper wire is good conductor of heat but bulb is bad conductor of heat.

We can assume the copper wire has reacted completely with excess sulfur being burned off when there is no longer any traces of yellow color sulfur in the crucible.

- the flask is protected - the liquid is heated more uniform
it went up because the mass increases
CuO + CH3OH --> HCHO + Cu + H2O
