'We have been very fortunate, Stip, for some of those fragments were indeed once part of this vase. I have repaired it as best I can, and the beauty it once had has returned in some measure!
'I have another task for you, Stip. There are tables throughout Rivendell on which pieces of art and history are sometimes placed for contemplation. Bring this vase to a table near Glorenglir. If she recognizes it as being the sum of the fragments you earlier uncovered for her, I shall agree to further her instruction as a scholar and give her leave to study some of the more valuable artifacts kept here at Imladris.
'If she does not recognize the vase, she will have received my final lesson. Place the vase on the table, observe her reactions, then return to me, and we will speak further.'

2. Glorenglir is in Rivendell.
Scholar Deluros asked you to gauge Glorenglir's reaction to the vase he reassembled.
3. Scholar Deluros is in the library of Elrond's House in Rivendell.
Deluros is waiting to hear if Glorenglir recognized the vase he reassembled.

Everything else should be fine. Carry on, adventurer!
