Diamine Oxblood Safe For Vintage Parkers?

[Arstook]

I realize the subjects of vintage pens and modern inks have been discussed to death. But can anyone confirm that Diamine Oxblood is safe for vintage Parker pens? I have a super 21 with a super clean sac that I would like to keep that way.

 

Thank You!

I don't know about Diamine Oxblood in particular, but:

 

- Diamine inks, in general, are fine with rubber sac pens

 

- The Parker 51 aerometric and P51 Special used a "pli-glass" sac, specially made for Parker by DuPont. They don't seem to wear out. (I don't know what material Parker used in the Super 21)

 

- If you fill a sac with ink, don't worry about keeping the sac clear. It won't stay that way long. Just now I checked the sac in three aerometric P-51s and a 51 Special. All four are dark.

Diamine have been making ink for over 150 years so I suspect their inks have been used in many pens that are now vintage. I've not used Oxblood in a super 21 but I know it doesn't permanently stain it's 30ml plastic bottle.

Any and all sac pens will be stained by any and all inks. Unless you fill a tiny amount and clean every day with pen flush, it won’t stay clean for long. Sorry to break this to you. If you are really desperate to keep it clean I think there are some brands out there that make unstainable sacs, but the names seemed to have slipped my mind. Hope I helped !

Thanks everyone for their two cents! I feel like I can trust in Diamine.

For whatever reason some people have found that Diamine inks can cause staining, but I wish you every success in using Oxblood in your Parker, perhaps you can surprise the doubters and show some before and after pics of your Parker.

I have used Oxblood in a few vintage pens and would say it is safe to use. As for staining, yes it will stain. Personally I feel that's a consequence of using ink, any ink.

I think that the OP said that their pen had a very clean sac, i take your point Jackflash that Diamine Oxblood will stain.

 

My advice would be to use a low saturated ink that is washable, try and keep the sac as clear as possible for as long as possible,

Rather a broad brush here. Washable inks, and inks like Pelikan blue and black are much less likely to stain a sac, if at all. The dye saturated inks however are likely to stain a sac.

[Fermata]

The 2010 review of Diamine Oxblood made the point that the ink was highly saturated.

Hmmm, I think I might be inclined to sticking with Waterman, Pelikan, and Sheaffer for vintage pens and getting Diamine for non-vintage writers.

 

Thanks!

How much is staining a problem in a Super 21? I found a Parker Super 21 in the back of my desk. The sac looks black, just like the pli-glass sac in a 51 Special (mentioning the 51 Special because the Super 21 seems to have the same sort of hoop filler). So is the sac in all the 51 and 51 Specials I have -- about two dozen. If you use this pen, the sac is unlikely to stay "clear" very long.

 

What would be the purpose of trying to maintain a semi-clear sac in a 21?

I don't know a purpose for trying to maintain a semi-clear sac in a 21, and I also think it won't stay clear no matter what ink is used.

[Fermata]

Sounds like an opportunity to see if this is true, I have a 51 that has been in regular use since the 1960s and that has an almost clear sac, does anyone have a 21 with a near clear sac?

 

I know that Diamine claim to have been making inks since the 1800s but my father doesnt remember them from the 1960s for example, nothing much before 2010, is this true?

[mitto]

I have a few 21s Super with super clear and almost clear sacs. But to be honest I dont use them much. And clean them thoroughly whenever I use them. And the pens are with me for the last almost 30 years. I also have 51s with almost clear sacs. I say almost because there is some slight ambering in the sacs but are still clear.

[Fermata]

Following Mittos comment I have done a search to see if I can find other examples of 21s with clear sacs, I think that you need to take a pinch of salt with the idea that the sacs are affected by whatever ink is used.

[mitto]

A couple of mine that I had easy access to at the moment. I may have at least 20 S21s with such clear sacs.

Yes of course Diamine's claims are true. Diamine Ink Company Cult Pens

Thanks Mitto, it would seem that all inks do not stain Parker sacs.
