Glass nibs


vermiculus

Recommended Posts

I've seen a few glass nibs in fountain pens. I don't mean the totally glass dip-pens, but button-fill and lever-fill FPs with glass tips.

 

How does the feed work? Here're some nibs on an ebay auction: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...em=180234118648. I imagine if you just stuck those into a regular pen, ink would simply pour down it. What controls the flow?

 

I'd love to see any picures and thoughts from anyone who has one. And anyone who has dismantled the feed of one, can you give me any insights? I was thinking that it would be a great project to mount a glass nib into a pen like a Esterbrook J (having modular nibs n' all).

I'm sure one of the experts will come along.

Meanwhile, I have a few SPOHRS glass nib pens.

There is no feed per se. The glass is twisted in such a way as to regulate the flow.

At least that's what it appears to be.

There is no feed. The nib is stuck directly into the section. Flow control relies on capillary action in the channels between the "flutes." The system works remarkably well; if it isn't chipped, a glass nib can write quite nicely. This is the nib on my Spors crescent-filler.

Richard, do you ever grind glass nibs?

Especially one of those super-flexi ones?

The moment we want to believe something, we suddenly see all the arguments for it, and become blind to the arguments against it.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
