Transparency Of Parker 51 Pli-Glass Sacs

[Lunoxmos]

So I have a Parker 51 aerometric, and I would like to be able to still see the ink levels in my pen even a few years from now. I am aware that the pen will get tinted from the inks I use no matter what ink it is, but is it possible that it can stay semi-transparent without getting completely opaque if I use safe inks ie Parker, Waterman, Diamine, etc?

It’s going to stain some, but you can still see the ink if you put it up to a light. Turn it upside down(nib up) watch the ink move around. After you use the pen for a while, you will just know by the way it writes when it’s time to top off.

For keeping the sac as clear as possible, Regular cleaning helps. Choice of inks is critical. Some are easier to clean than others and some highly saturated inks are more suited to cartridge / converter pen. Waterman Serenity blue will wash out of your pen with plain water and not leave a trace.

I’m very fussy about what i put in my Areo P51’s. The plyglass sac is pretty tough, but, having played around with different inks, these days i only use Visconti blue, Aurora Blue Black, or J Herbin Bleu Des Profondeurs. The Herbin is a wet flowing ink, it cleans up easily and is particularly attractive to some of those ink stingy fine nibbed P51’s. Turns them into a different pen with a nice color saturated ink line. Right now i also use the Herbin in my P51 Vacs and am real happy with it.

Hope this helps. Get back if you have any other questions.

I have been fortunate to buy and use a few NOS 51s. I use only the regular inks from Quink, Waterman, Pelikan and Montblanc. The sacs do turn progressively opaque, I will post a pic later of one of the sacs if you are interested.
