A Weird One: The Sweating P51 Sac


Malice

Recommended Posts

Now I have a weird one for all of you:

I recently bought a navy grey Aerometric filling P51 mk2.
Somewhere along it's lifespan, the pli-glass sac was replaced by a latex sac.
After cleaning it, in the fashion described in the pinned topic, I used it for a week with Sailor Gentle grenade. Not a single problem.
I cleaned it again, and since two weeks filled it up with MB Friendship.

And now it gets weird: It is like the sac is sweating.
What I mean by that is everytime I use my pen for a while, a sort of mist appears on the sac in the ribbed bar hole. This mist is barely visible to the naked eye, but when I wipe the sac with a tissue, some blue clearly transfers.

Anyone have any idea what this is ?

I can't account for the blue part.

 

But,

 

IF for example, you were carrying the pen in a pocket or where it was next to your body it could attain a similar steady state

temperature as your body while there of around 100 F. (- a bit) Now, if you happened to be storing your ink somewhere

where is was very cool, I could see the "sweating" being temperature related such as that which forms on a warmer glass

when cooler liquid is poured into it.

 

That's just a pure SWAG though. ;)

The sweating is most likely a temp related thing as Bruce described. Going from a hot outside temp to an air conditioned environment could cause it. The blue is possibly the remnants from an old spill if you can't find that the pen is leaking. A little ink can go along way.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
