What is Ebonite….
The name “ebonite” comes from “ebony” and is black in color (duh). Yet it is clear brownish-red in thin-film form and brownish-red in powdered form. Also known as Vulcanite, it is warm to the touch, a durable medium, and provides excellent electrical insulation and machinability. Great, I’ll remember that next time I’m working with live electrical wires. Ebonite is sometimes called “hard rubber,” manufacturers in Germany and Japan often distinguish ebonite that is hardened with fillers from “natural” hardened ebonite.
Eco-friendly benefits of ebonite, it is manufactured with natural rubber collected from gum tree sap, and the tree is not cut down. Gum trees have a high absorption rate of carbon dioxide.
Ebonite is produced by a chemical reaction of combining rubber and sulfur molecules in a process known as “vulcanization.” Ebonite may contain from 25% to 80% sulfur and linseed oil. The process is accelerated by applying heat and pressure of steam for several days. The result of the process is low-elastic, very firm vulcanized rubber Interestingly, soft ebonite prior to vulcanization becomes ultra hard rubber afterward. When the surface of ebonite is polished, it gives a beautiful, lacquer-like gloss.
Why do I love ebonite pens, especially those that are dyed or mottled, etc. Welp, when the surface of ebonite is polished, it gives a beautiful, lacquer-like gloss. Secondly, the pen has a natural warmth to the touch, unlike contemporary acrylic, plastics, or vintage celluloid which are cold. I am particularly fond of ebonite which is mottled – mixing colored rubber with standard rubber in the vulcanization process.
Following careful mixing formulas, ebonite rods can be drawn in a spiral fashion to produce a variety of appearances and styles.
As the technique gained popularity, pen makers in the 1920s produced elegant woodgrain pens.
Expanding the woodgrain design, in 1926 Waterman introduced a flow pattern, called ripple. The only other company to produce a true ripple was Platignum.
“Ripple in still water. When there is no pebble tossed. Nor wind to blow”
~ Jerry Garcia
Ripple was immensely popular and available in a variety of colors such as olive, rose, and blue-green. Contemporary mottled ebonite rods available to indie pen manufacturers come in a fantastic range of colors. The rods are readily available from manufacturers in India, Japan, and Germany.
Unfortunately, black ebonite is susceptible to sun and water damage. I have not encountered this with mottled, woodgrain, or ripple ebonite pens. Maybe I am just lucky.
