Outgasing? Il gas ha mangiato il celluloide? Anche umidità?

Tom, tienici il vino in cantina non le penne!

Che disastro!
Che dolore vedere due penne stupende ridotte in quello stato.
Credo che per riportarle in vita ci vorrebbe un vero miracolo. Anzi, due.
Quello della cristallizzazione è un fenomeno sul quale ci sono più ipotesi che certezze, ma sicuramente l'ambiente deve avere influito parecchio.
Temo che il massimo ottenibile sia recuperare pennini e qualcos'altro....

Queste due Tibaldi vanno bene per il cassetto dei disastri! Possono fare compagnia all'Etiopia Grigio-Viola!

stranamente, si e rotta solo la Trasparente - la Iride - corroso fermaglio e verrette,
ma il celluloide senza danni.
solo al interno, il gommino dell meccanismo si e ridotto a pezetti. allora, Iride si puo salvare.

Una cosa che mi pare assodata è che la celluloide più è trasparente, più è soggetta a cristallizzare.
Se la Iride non ha avuto questo tipo di problemi, sicuramente dovrebbe essere recuperabile; anche nella clip non mi stupirei se la doratura fosse molto meno compromessa di come potrebbe apparire.

L'ho trovata: http://cgi.ebay.it/Sold-As-Parts-OMAS-75th-Anniversary-Ercolessi-LE-FP-NR-/150584377822

L'asta è chiusa, ma le foto ed i link nella descrizione vanno ancora. Lo stesso tipo dei danni. Il venditore aveva un'Arlecchino nello stesso condizione.  

Tom, my Visconti Voyager Anniversarys (modern celluloid) were stored in a Delta zippered case left partially unzipped to let the gas out. But after some months, I noticed white/green oxidation on the clip, emerging from underneath the sterling silver plating. The pens, the celluoid, felt slightly damp/wet; I could wipe it off. I cleaned them up, then put them back in the zippered case. 3-4 month later, there's oxidation again with the same damp feeling on the celluloid. There were some other celluloid pens in the case -- mostly old Viscontis made of vintage celluloid -- but none showed any oxidation on the clip nor did they feel damp to the touch.

I'm not sure what is happening with the celluloid on those modern Viscontis, but I decided to store them separately and differently. I suspect if I had not checked on them, they may have eventually shown the same damage as your Tibaldis.

HI Eric, I got a message from Visconti, they said, yes, they knows about this - it does not only happen only in closed boxes - but mostly. and Mazzucchelli, they have no clue, what is the process behind this. Anyway, a bath in Lye to neutralize the acid is alway recommended.

Thanks Tom. It's a known problem.  

Lye!?! Doesn't that burn human flesh? A bath in lye doesn't sound like something I should try at home in the kitchen sink. I'll keep an eye on these, if they keep doing it I'll send them to Visconti.

well - a moderate solution of base - some NaOH - not the solid pellets of Soda Caustica thrown over the pen - that would sure neutralize - give it a try.

Visconti wouldn´t do it differently.  if they ever did such an operation....

Ok. But can't I just put the pen in a Coca Cola bath? That stuff works great for removing some kinds oxidation (I'm not joking), supposed to eat teeth too. Maybe that will work?!? Any left over I can drink.
