I. uhh, got a pomarico sapphire crystal mouthpiece for my birthday. Wasn't expecting it, it just arrived. :-D Anyway.
I have a slight problem with it being stuck on my barrel currently. I did cork grease it before I put it on, but obviously its not done much for me removing it >.<
Anything I can do?

take it to a tech/repair person. Best not trying and get a crystal mp off yourself-you could break it. Also, if you drop it, goodbye mp. Best take it to a take. They might even do it for free! Good luck!

Meh! Thanks for that, I guess I'll have to do that. I really don't wanna mess around trying to get it off in case I do break it. It's worse if i break it being a Bday gift.
Is it a desperatly must get done ASAP thing, or can I leave it till I next get up to the repair shop?

The very soft "greasy" cork greases have a tendency to get absorbed and quickly lose their lubricant effectiveness. Van Doren and a couple other brands are very firm in the tube and more waxy and really work better longer.
Do NOT leave it until the next time you go to the repair shop. If you do, you may NEVER get it out. ASAP is the watchword.

It won't twist either? I had a mouthpiece do the same thing, stick inside a barrel and seemingly would not come off, but after some twisting while holding it with a pair of gloves with gripper things, it loosened up enough to wiggle out. It wasn't a glass mouthpiece though, so take what I say with a grain of salt. The repair tech will have a better answer, if you get it there soon.

Phew! It's out. We phoned up tech guys who said to stick it in the fridge for half an hour, then try. If that didn't remove it to bring it up.
After 20 mins it still was quite warm, so I put it in the freezer for 5 (standing up so nothing touched it) then using a damp towel I managed to twist it off fairly easy.
I'm gonna sand down the cork a little shade because I don't want that to happen again... Ever!
Thanks for the help. This boards great!

Are you sure it is just a matter of too much cork? There have been previous discussions about difficulty with barrels getting stuck on the top joint. That happened to me and it was wood binding on wood. The only solution was to remove some wood. (I did NOT attempt that, I had Morrie do it) Have not had the problem since. I would suggest taking it to a tech to determine the reason for your problem. It may be that your barrel needs to be reamed out slightly.

I guess sanding down the tenon of the Pomarico is gonna be tricky ;-D
Why does the freezer thing work?

It was the cork. I sanded a little off in the middle of it, and whilst I wouldn't trust it to sit in there for several hours without checking I can move it (which i do), it is a little easier to get in and out. Still using a lot of cork grease for safety!
Heat expands things, cold contracts it. So I guess thats why it works. Freezer is just colder, faster. I might have left it in the fridge for longer, but I had to go out fairly soon.
It was just choice about the freezer, a quick fast freeze, as apposed to a cool breeze that chills slightly *G*

The shrinkage of crystal in a refrigerator would be very small indeed, and it is fairly likely that the low humidity would shrink the timber of the barrel, not to mention the very small shrinking of the metal socket ring.
I would be a bit careful with freezing wooden parts. The low humidity, I believe, has the POTENTIAL to grab moisture from the outside of the timber, which is what makes timber split. Also, if the inside of the timber is wet, and water expands as it freezes, then this would contribute even more to the stresses which cause splitting. It may be fine some of the time, but for timber that is already stressed, as it is with a jammed tenon, the additional stresses could be the last straw. I rather suspect that the loosening by cooling comes from shrinkage of the cork itself (seeing it is mainly air), or something that happens to the grease, or just the operator applying renewed effort.
I have not yet come across a mouthpiece that a stronger pair of hands cannot remove.
"Do NOT leave it until the next time you go to the repair shop. If you do, you may NEVER get it out. ASAP is the watchword."
I have never met a joint that cannot be removed, even after decades of being stuck.
"I'm gonna sand down the cork a little shade because I don't want that to happen again... Ever!"
If you are using a decent cork grease such as Alisyn or those from Doctor's Products, then the cork grease will be such a good lubricant that it will be rather difficult to sand.
"Are you sure it is just a matter of too much cork?"
I would be asking that too. I'd say it is pretty well impossible for a greased cork to get stuck in less than a few years, when a low grade cork will polymerise and turn to glue. On the other hand, applying more grease after sanding a cork can give the ILLUSION that the problem was the cork.
"I guess sanding down the tenon of the Pomarico is gonna be tricky ;-D"
I don't know about Pomarico, but O'Brien crystal mouthpieces had a sharp bur on the tenon, left over from between two halves of a mold. O'Brien never removed it, and it chewed away at the tenon socket. I removed such burs with a tiny, high-speed diamond saw in my dental micromotor unit.

There's not much an old toothbrush and a bit of houshold soap can't remove...while I have a certain pride in our local grease, I must confess that a two-minute treatment with aforementioned tools removed enough old and new gunk to make the cork perfectly sandable after drying.

Fair coment. To be fair, I have never devoted a whole two minutes (+ drying) to the grease removal.
I use a certain particularly sharp, large bur in my dental micromotor handpiece.
