Ball point pens Answered

Does anyone have any ideas about refilling a favourite ballpoint pen with ink? I have thought about using a syringe, but the ink is too thin. Before anyone asks, I can't just buy a replacement refill for the pen as they stopped making them.


A syringe sounds like it would be perfect. How thin is this ink if a syringe won't control it?

Well re the viscosity of the ink, the problem is that the ink in ballpoint pens is as you know, very thick. The only ink I have access to is the bottled type that people put in old fashioned pens with a nib. I suppose what I need is someone to tell me how to thicken ink to the same consistency as ink found in ballpoint pens.

Do what kiteman said or add cornstarch to the ink to thicken it a little, with the cornstarch a little goes a long way...

Hmmm, arrowroot might work better, as cornstarch may clog the point...

Aye or even just thicken it with heat, gently heat for a few minutes to drive off water...

Depending on the brand, I would be careful with that...a lot of our ball points do not have water soluble ink, so assuming a solvent of some sort, one would have to stress "gently heat"; or expect to create a small torch or candle out of it :-)

That sounds fun to try, in a well-ventilated, non-flammable environment.

Ink is, if it burns at all in that narrow tube, quite a slow burn :-)

But if you take it out of the tube...?

still, if one wishes to thicken it, but rather ignites it......well :-)

No, you simply have to suck the ink out of another ballpoint pen.

Uniball makes ballpoints that use thin ink like that. Maybe the ballpoint is machined a bit different, but if you get a good cap on it, I bet nay pen could hold and work with the thin stuff.

I take no responsibility for any stains resulting from the taking of my advice

what about if makes it your favorite?

It is designed so you will never accidentally put in into your pocket with the tip of the pen extracted. As soon as you push the clip onto the top of a pocket it retracts the writing end automatically. But the real reason is that I like the feel of how it writes and the line it makes when writing is very fine, (which is why I want to refill it rather than just put a similar refill into it).

You'd be surprised how many refills fit other pens. Take the empty refill to a decent stationers and wander around the pen aisles.
