Precious resin, ebonite, cotton resin, acrylic resin ...

Precious resin, ebonite, cotton resin, acrylic resin, fairy dust, etc.

 

How much of this is legit, and how much is a fancy word for plastic? ;-)

Well, ebonite is not plastic.

 

There are subtle differences between some plastics, but the differences really are in how they work on the lathe.

 

My opinion is that there is very little difference in the durability, wear resisitance, and how well a pen takes a shine when you look at plastics that penmakers use.

Resin is plastic. The resin industry (which I'm in) is filled with euphemisms to make things not sound like plastic. Fillers are added to resin so "bonded bronze" can have real bronze powder in it but the amount can vary. Things like ground pecan shells are added to resin so that products can be represented as made of a more natural material. There are no consistent industry standards -- the names are made up for marketing purposes.

Ebonite is plastic in that it is a synthetic polymer. I'll grant you, it isn't PVC or injection mold plastic, but plastic it is. Ebonite was developed to replace ebony. The process involves inserting a number of sulphur linkages into rubber to create a more structured material.

Gotcha...thank you.

It's not synthetic, but I'll grant you that it's semi-synthetic and thus still plastic. Ebonite is pretty much in the same category as rayon and lyocell.

plastic: a synthetic material made from a wide range of organic polymers such as polyethylene, PVC, nylon, etc., that can be molded into shape while soft and then set into a rigid or slightly elastic form.

 

resin: a sticky flammable organic substance, insoluble in water, exuded by some trees and other plants (notably fir and pine).

 

synthetic resin: a solid or liquid synthetic organic polymer used as the basis of plastics, adhesives, varnishes, or other products.

 

precious resin: ????

 

cotton resin: ???

 

acrylic resin = acrylic = synthetic resin: of synthetic resins and textile fibers) made from polymers of acrylic acid or acrylates.

 

ebonite: another term for vulcanite

 

vulcanite: hard black vulcanized rubber

 

rubber: a tough elastic polymeric substance made from the latex of a tropical plant or synthetically.

 

vulcanize: harden (rubber or rubberlike material) by treating it with sulfur at a high temperature.

 

fairy dust: ????

 

 

So, "resin" is not plastic, "synthetic resin" is plastic, and "ebonite" can either be natural or plastic. Then the question is, again, whether MontBlanc, Omas, etc., they mean natural resin or plastic, as the terms "precious resin", "cotton resin", and "ebonite", could very well mean "plastic". This is a very good question...

Any ebonite from after the second World War is almost certainly fully synthetic, a petroleum derivative. Any ebonite pens you may buy today, perhaps with the exception of some high-end artisanal Danitrios, are synthetic. The cost of harvesting rubber, purifying it, and then treating it at a chemical plant is price prohibitive vs just synthesizing the whole item in-house.

I quote that for "resin", and then, again, are they selling us expensive "plastic"?

No, no, no. Montblanc pens are meticulously crafted from precious resin for a high lustre finish with outstanding scratch resistance. A discerning customer like yourself can clearly see that our precious resin isn't related to plastic...

I like MontBlanc's resin, do not get me wrong. However, one cannot ignore the general doubt, given that MontBlanc does not specify what "precious" means. There is also a good number of people, also at FPN, that raised the same question. Then, again, is MontBlanc's "resin" natural or synthetic?

Hi,

 

Precious resin is probably a synthetic material with glass filler. Maybe someday we can get a definitive answer, but we'll leave it at that for a moment.

Stolen: Aurora Optima Demonstrator Red ends Medium nib. Serial number 1216 and Aurora 98 Cartridge/Converter Black bark finish (Archivi Storici) with gold cap. Reward if found. Please contact me if you have seen these pens.

Please send vial orders and other messages to fpninkvials funny-round-mark-thing gmail strange-mark-thing com. My shop is open once again if you need help with your pen.

Will someone with the name of "Jay" who emailed me through the email system provide me an email address? There was no email address provided, so I can't write back.

Okay, I'll grant you that ebonite after some period is fully synthetic.

 

On the natural vs. synthetic resin front: of course there are natural resins, such as those traditionally used on bows. Shellac and natural lacquers are others. That said, most resins these days are synthetic.

I'm a fan of acrylic. Okay, it's cheap, but it's also strong, stable, light, and can vary from transparent to very colorful. There are desirable qualities of other materials that acrylic can't replicate, but based on acrylic's characteristics of goodness and cheapness I have to regard it as a winner.

The Sailor King of pens is advertised on Sailor's website as being manufactured of "natural rubber", so is it not really?

If they name it so, it may well be. It is more expensive and they are showcasing its origins to make up for this. If you just buy run of the mill ebonite though, or most plastics for that matter, you are most likely buying a petroleum distillate product.

Naturally!

Does ebonite (real or synthetic) absorb or hold ink in its structure to assist in the flow of ink to the nib?

There has been discussion that ebonite feeds do so, whether this is from the ebonite itself or from the manufacturing process, I don't know. I'm sure someone on here has got the answer though!

      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..
    • A Smug Dill
      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
