EBONITE

History and production
Ebonite (whose name comes from ebony) is the result of the meeting of 2 elements:
rubber and sulphur.
At the beginning of 20th century, rubber production expanded widely (the worldwide production was multiplied by 4 between 1900 and 1910), notably through the emergence of Asian plantations (providing today 99% of the total production), competing with then majority producing South American plantations - the French word caoutchouc, i.e. rubber, comes from the Quechuan words Cao (wood) and Tchu (crying) –

The ebonite industry went through a revolution thanks to 2 major discoveries:

American Charles Goodyear in 1841 and Britton Thomas Hancock in 1842 perfected the process of rubber vulcanizing.
Natural rubber has a liquid consistency and sulphur (30 to 50% of the mass) is added at high temperature in order to thicken the rubber. The proportions determine the final elasticity and life length of the resulting ebonite.
 
The end product is shiny, glossy, and black and can resist external temperatures of up to 50°C.
It is usually processed and delivered in bars or tubes.
Apart from being used in pens, ebonite has been used in discs (called Berliner), buttons, combs, jewellery, musical instruments, etc.
 
Characteristics:
Above all, ebonite is an extremely robust product (very useful against corrosive inks), little heat conductive (thus limiting the leakage risks due to hands’ heating) and non-porous (in the first pen models, the body itself was used as an ink tank).
 
But take care! Ebonite does not like intense heat, light or water. In the presence of any of these elements, sulphur will leak and the ebonite will become dull and crumbly. The olive colour observed on old pens comes from rubber oxidation (due to moisture, formation of sulphur oxides and sulphuric acid).
NEVER USE WATER!

About pens:
Most of the pens you might encounter will be of a black colour (olive colour in case of a slight fading) or brick-red colour (for instance, the brick-red Parker Duofold marketed in 1921). There are however some two-colours models, black and red/blue/green/olive (for instance, the Waterman Ripple, launched in 1923 to compete with the Parker Duofold).
 
As for the black models, the manufacturers did their best to fight against gloominess! How? By using 2 techniques:

By coating all or part of the cap with various metals (gold, silver, etc.).
The models with a visible black body are often named “filigree”.
The fully coated models are often named “overlay”.
By printing geometric patterns on the ebonite (bars, checked designs, etc.).

This fashion will last even after the introduction of celluloid (in 1920’s).

 

CELLULOID

According to history, the celluloid discovery is linked to 3 events:

  1. The Secession war and an embargo on natural ivory imports.
  2. Two wealthy snooker players who, frustrated by this embargo, organized a competition to find the best substitute to ivory.
  3. A contestant, John Wesley Hyatt, whose brother managed to create celluloid in 1870 (mainly made up of cellulose nitrate and camphor).

Later on, around 1884, the paternity of this discovery will be attributed to a British inventor, Alexander Parkes, who carried out similar experiences a few years earlier (1856: Parkesine).
 
Celluloid is considered as the very first artificial plastic and it is still used nowadays, in the making of ping-pong balls for example.

Characteristics:
Celluloid is very robust and can be easily coloured.
When scrubbing a celluloid pen to polish it, you instantly have a strong camphor smell.

WARNING!!
Celluloid is extremely flammable…!
If you want to split the nib’s feeding tank from the body of a celluloid pen, you must take extra care (soak the tank in cold water or use a hair-dryer).
Also, for some colours (like jade green), there are real risks of pen’s bleaching and you must then either use a non-noxious ink tank or not use your pen!
 
About pens:
As soon as celluloid appeared, the colour was used on pens.
The colour range was not very wide in the beginning (yellow, black, red, orange and green), with types like Permanite (Parker) or Radite (Sheaffer). Great efforts were made to advertise the sturdiness of the products (Parker, for instance, threw pens out of planes, or from the top of buildings).

GALALITH : Thanks to the cows !

History and production
History is sometimes amazing … in pharaohs’ ancient Egypt casein (the milk protein) was already playing an essential role for writing by fixing ink on parchments. But if you let a milk bottle open during several weeks, you will easily understand why the non-degradation of casein gave a real headache to the inventors of Galalith.

How to replace the traditional blackboards and chalks by an erasable synthetic material in … 1900 ! Krische (a German printer) and Spitteler (an Austrian chemist) worked on it and filed the first patent in 1889.
The French chemist Jean-Jacques Trillat put the finishing touches when he discovered the way to make casein insoluble by adding formalin (immersion process), thus making possible the preservation of this matter.
To make it short, you take one litre of milk, containing about 30g of casein, you add formalin and colourings … and you get Galalith.
This new plastic was presented at Paris Universal Exhibition in 1900 !

Characteristics:
In France, Galalith was distributed by the Compagnie Française de Galalithe located near Paris in Levallois-Perret. The Jura area became the first one to use this matter in the making of several products: buttons, pens, jewellery, umbrella handles, …
Galalith was available in the form of rolls or plates. Thanks to its natural porosity, the manufacturers could easily colour it. However, since it could not be moulded, this matter requested an important work of polishing, either manual or mechanical, in order to make it shine. It became famous for its ability to imitate ivory, amber, horn, tortoiseshell, wood, …
 
However, its cost as well as the development of other plastics led to its disappearance.
 
About pens:
Most of the pens manufacturers used Galalith; Parker even renamed it Ivoirine (Ivory). When rubbing a Galalith pen, a characteristic smell will emanate from it.  In the past, some even said that during strong heats the pen would get a smell of sour milk (I personally never noticed that).
 
Casein tends to degrade over a long period of time; some cracks might appear and the colour might fade. However, I must point out that these problems do not occur with modern Galalith pens, thanks to new technologies. With old models, the main worry is linked to porosity, since a leak in the ink bag might result in the ink’s diffusion and a colouring of the pen’s body. You might polish manually a Galalith pen as long as you use a neutral paste (non coloured). The storage precautions are the same as the one used for Ebonite pens (away from light, heat and moisture).
