Rotring drawing ink?

[Bo Bo Olson]

I'm pretty sure one can't use Rotring drawing ink in a fountain pen.

 

I looked and couldn't find a thread on it....or drawing ink's use in a fountain pen.

I landed a couple bottles of Black and one of Blue, in a shoe box with a couple pens. The ink is from back in DM days...pre 2000 when the Euro came in.

They are in a plastic long spouted square flat bottle.

In no one does draftman's work outside with a computer. If I can't use it in a fountain pen**....I don't know how to get rid of it...properly..

 

** I'd not use the black, in I still have half a bottle of 4001 black from 15 years ago.

Geologists use it for field mapping, or at least did when I was an undergrad, maybe you could donate to a nearby University Earth Sciences department

Good idea, Heidelberg should have such a program....we called it Geology when I took it back in the BC.

Some German Universities specialize in one thing, others another.

You can if you're brave enough. Rotring blue has a kind of a unique colour (at least had) and covering power, no shading, I absolutely adored it (and should try to get some).

Expect frequent cloggings, a pain to clean, etc. Use it only in a pen that's easy to dismantle and clean, a cheap pen, or a Lamy where you can pull the feed easily to clean it. The cleaning solution sold by various brands (Koh-I-Noor Rapido eze for ex) will help. Expect some staining on some plastics too.

I 'knew' it's a lot of trouble.

Where are you at? North pole. Europe, America.

I could ship it too you... Not this month...and half of next month I have eye operations coming up.

Try it in a cheap pen before

See if you can find a technical {drawing) pen. Rapidograph, Stadtler Mars 700 or the like. I picked one up a few years ago on US eBay for under $10 USD. They are designed to use it anyway. I have both a 3x0 (.1 mm) and a 4x0 (.18)

I was wrong, my memories were of the Staedtler equivalent of this ink. Rotring drawing ink blue has the same "qualities" (mostly waterproof once dry, smooth writing, well saturated) but is a bit darker than the Staedtler:

 

 

I have it in a Lamy Safari clone at the moment, with a Lamy Z55 EF in the mini sample above. I wonder if something bad will happen to the pen? So far it works really well and isn't even that prone to hard starting!

 

The Lamy converter wasn't stained at first contact, but my hand, nails and sink were, from ONE drop of already diluted ink that I rinsed immediately  

 

Oh and in real life colour and aspect once dry are really close to Pilot blue (in a relatively wet Parker 45 "EF").

Now I'm on the hunt for some Staedtler blue...

Good luck.
