No overflow - no problem?

Hi,
I have a copper sink in the bathroom and because it doesn't have an

The lack of an overflow doesn't cause sinks to drain more slowly. Your
slow draining problem is due to something else -- possibly a
partial clog somewhere in the drain line, or maybe because the sink
is not close to a vent pipe.
Right. The (partial) clog is somewhere down the drain. Water in the sink
hits the clog and backs up, like a dam, then proceeds at only the pace the
miniature spillway permits.
A dose of concentrated sodium hydroxide (lye) will bust up what the
miniature beavers have built.
The question of a proper vent can be answered by asking another question:
Did the sink ever drain properly?
