Diamine nib crud

[mac47]

I have an orange Diamine ink that leaves crud around the edges of the nib. The longer it goes without writing, the more crud there is. It always washes away OK, but I haven't dared to out it in one of my favorite pens yet.

 

I've tried searching the forum here, and found some discussion of the same phenomenon, also for an orange from Diamine, but there was no definitive answer about whether this ink is safe. I'm treasure my 51s, and I use them as daily writers, so I don't want to damage them with an unfortunate ink.

 

Any definitive word on this Diamine crud?

 

Thanks in advance.

Is it Diamine Pumpkin? There are numerous reports of this particular ink leaving crud on the nib and feed. Personally, it's not an ink I would use for that reason.

Diamine orange does the same for me, it's a shame but still a great colour.

The crud is almost certainly dye left behind by evaporation. This happens with extremely saturated inks. I have a bottle of Levenger's Cocoa that does this. It is probably safe enough if you don't allow the ink to dry all the way back to the feed channel. You could try adding water to the ink. With an orange ink, though, diluting the color may make it too light on the paper.

It's just the regular Diamine Old English Orange, not the Pumpkin, which is darker. I got it not least because I love those Diamine bottles.

 

Found another thread about this ink here, with a review by Stephanie. Looks like the deposits on the nib are pretty common. No reports of anything more untoward than that, so I think I'll fill my fine-point 51 with it and grade some students' papers. (I'm a high school teacher who grades everything with a fountain pen.)

I tried Pumpkin in a Esterbrook SJ. It did the same thing, washes right off though. I don't know if I'd worry about it too much. I found J.Herbin 1670 doing the same thing on the Wing Sung 237 I put it in.

I've had this behavior / problem with both Diamine Orange and Pumpkin since I first stated using them.

It is unsightly and messy, but as far as I can tell, not causing damage.

I have found that my pens with caps that seal tightly do not exhibit the crustiness, so I don't normally have issues.

Yes, I wouldn't worry about it, Diamine ink and any associated crud is generally very easy to clean out.

 

eta: which reminds me that I should buy some more

I've heard the nib crud reports from Orange, Pumpkin, Poppy Red. I've also had very MINUTE nib crud formation from Sunshine yellow, which leads me to believe that its the pink component that's present (Don't have poppy red though) in all of them.

I have had this happen with Diamine Orange too, but only with pens that have caps which are not at all airtight. I also don't think it causes any harm, since it comes off easily.

i get that from diamine BB and still use it in all my pens w/o problems.

I don't think it should be too much of a problem. Crud from diamine oranges dissolves and washes away easily with water. However, after using Diamine Pumpkin in a pen, I had to do an ammonia flush on the pen before any other ink would flow in that pen. In any case, it's nothing a good cleaning won't fix if you do happen to have problems.

Same problem here with Diamine Orange in my Lamy Safari (fine). I love this pen and ink combination for highlighting in books. I am happy to hear it doesn't seem to impact performance.

So... I put it in my fine P51 and... No crud. The cap is apparently airtight enough, and the hooded nib probably helps.

You probably won't have any problems. If anything happens it'll wash off with water. Worst case, all you'll need to do is a flush with some ammonia added.

I have noticed that on my "51" Special and Special Demi both when using Diamine Blue Black, but it doesn't seem to effect writing and cleans right off. Overall I still really like this ink.

can you use FP ink to highlight? i mean, book paper is...bad.
