When copper is pulled into thin wires, it is called copper wire drawing. This process involves passing the copper through a series of decreasing diameter dies to gradually reduce its diameter and form a thin wire.
No glue is used for copper. Copper wires and pipes are soldered together. This involves heating both pieces and melting a lead/tin wire into them.

how much copper is in copper wire
No. Copper wire is a solid
No.. Copper wire isn't
No, copper wire is not magnetic.
Copper wire sent for recycling is remelted and rerefined. It becomes a new copper product one of which might be new copper wire.
Generally speaking, the copper is the wire. If it is coated, it can be stripped in small sections, but if you need to get rid of a large amount of plastic insulation, you will have to find some safe way to burn it off. Safe, in this context, means in a place where the fumes ( which are toxic ) won't bother anyone, and the metal can be removed without danger- preferably after it has cooled.
If you mean a bare copper wire, that is the "ground" wire.
Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.
The ability of copper to be drawn into a thin wire is a physical property, as it involves a change in its physical state without altering its chemical composition.
