Natural rubber

Thank you. Nice to hear from a hard rubber manufacturer. I've always been fascinated by the mold work involved in your industry. I think that it is the skill involved that has always made saxophone players believe that each mouthpiece must be individually created by hand, whereas in reality, it is only the final tweak that is done by hand. You can see from my blog what my opinion is of hyperbole. Still, I'll take the compliment. Great article this practice is done with so many products to make claims of rarity its a "hoax on the folks".

Great article! This practice has been used in many products to claim rarity thus driving up the cost its a "hoax on the folks". Are the recipes lost in the dim past and can't be replicated today? Heat doesn't transfer like it used to? There's neither proof nor logical justification for these types of claims.

For a basic outline of the vulcanization of natural rubber to create " ebonite " or hard rubber, check out this video with a saxophone backing track and a voice-over by a woman who really, really likes vulcanization. The flexibility or hardness of the rubber is basically in direct relationship to the amount of sulfur in the recipe, although other additives were later used to produce different properties.

Ebonite was first used because of its resemblance to the ebony wood originally used for woodwind mouthpieces. That's the benefit of hard rubber; it machines more reliably than ebony, it is more stable, and it is less expensive. As an added benefit, with an investment in the proper equipment, it can be molded into a blank that eliminates much of the preliminary machining, including difficult chamber work.

It's final advantage to some is that it feels like wood in the mouth. Many people prefer it to the feel of metal or plastic. Originally, ebonite was processed in the same manner as ebony for making mouthpieces. A hard rubber manufacturer molded ebonite in a dowel shape, called bar or rod rubber, and the rod was cut into sections and machined by the mouthpiece maker just like making a mouthpiece from a piece of ebony wood dowel.

Mouthpiece makers in the early s were already set up to machine ebony wood, and by purchasing rod rubber, the same milling process could be used.

On the other hand, milling rod rubber means that the maker doesn't have to make molds, mix raw ingredients, cook the rubber in an expensive autoclave for many hours , etc. If you had expensive and complex milling machinery, and were adept at milling, you would claim that rod rubber made superior mouthpieces.

If you had expensive and complex equipment for molding, and were adept at molding, then you would claim that molded hard rubber mouthpieces were superior. That's the difference in the two processes. Or at least, that's all we have evidence to support. We know that there is no discernible difference because several of the most respected vintage mouthpiece makers went back and forth between molded and rod rubber pieces, as shown in this blog.

Notice that "rod rubber" is molded rubber. It was molded into a rod shape and then milled. Although some claim that there is some kind of physical difference, when you examine the manufacturing process, it is clear that the material is identical.

Also notice that I did not make any acoustical claims for hard rubber, whether molded rod rubber or molded blanks. For that, we would need extraordinary evidence, of which there is none. There is some anecdotal evidence where people have claimed that they clearly hear the difference. But we are back to the Princess and the mouthpiece type of story discussed in an earlier blog. You say that hard rod rubber is acoustically superior? Then that shall be my proof! Next, we are making a production run for Woodwind Co.

Puis, we make some Revelle pieces for sales by music stores both here and abroad. What recipe should we use for those? The good Chedeville recipe or maybe the inferior Vito recipe, no? Where is the evidence that any blank manufacturer ever changed their recipe for individual customers? Where is the evidence that any rod rubber producer changed their recipe for each mouthpiece customer or even had a "mouthpiece recipe? I don't believe that woodwind mouthpieces ever drove the production of the type of rod rubber that was being produced.

Woodwind mouthpieces comprised a tiny fraction of the mouthpieces made of hard rubber. Smoking pipe mouthpieces i. And a new-fangled device called a telephone required the production of a thousand times more hard rubber mouthpieces and ear pieces than did the saxophone industry. The best being those that were milled from hard rubber rods, but of course. Molded ebonite mouthpieces, especially the improved production techniques of Maurice Riffault in , with further improvement in the 's when his daughter, son, and son-in-law joined the business, must have been tough competition for rod rubber mouthpiece makers, as is evidenced by the vast majority of makers and saxophone companies turning to molded pieces.

By the 's and 40's, rod rubber mouthpieces were as rare as hen's teeth. That's because makers had learned that there was no advantage to milling from rod rubber although some would still claim that they were using some secret process like "eburnated bar rubber" without admitting that it was a molded blank.

Because of some early hype about the superiority of mouthpieces milled from rod rubber, many vintage mouthpieces sold today are claimed to be made from "superior" rod rubber. That's false on two accounts. First, there's no evidence that rod rubber produces a better mouthpiece. In fact, most claims about how mouthpiece material matters are demonstrably false.

Second, there are very, very few vintage pieces made from rod rubber. In the U. But huge advances were quickly made in the molding of hard rubber. Automobile tires were one use. AHR is where Arnold Brilhart bought his first molded blank mouthpieces for the creation of his hard rubber line of pieces.

At some point, definitely by the 's, reduced costs became an even larger factor in mouthpiece marketing as in the case of general saxophone production and there were more "student grade" mouthpieces, just as there were more student grade instruments. One of the things that's really strange is that the perceived quality of the vintage "super special hard rubber" seems to vary between saxophone and clarinet players.

But for clarinet players, a piece marked just Riffault is generally thought of as "better" than it's identical brethren marked with a trade name other than Riffault of which there are many, including Bundy. The exception seems to be the common Riffault pieces marked Chedeville. Here's a recent Ebay auction for a Riffault clarinet piece in a standard facing. Unknown February 22, at AM.

Modern bowling balls utilize a two-part construction. The bowling ball usually comprises a large, spherical inner core formed of rubber, natural or synthetic, with a substantial quantity of inert filler; some cores may be formed with resins not ordinarily classified as rubber.

Technical Field The present invention is related to liquid ebonite mixtures and, more specifically, to coatings and rubber concretes formed therefrom and to methods of producing such mixtures, coatings and concretes. Ebonite is the product of the vulcanization reaction of synthetic or natural rubber high molecular weight cis-1,4- polyisoprene with an excess of sulfur. Typically, the rubber vulcanization process takes place when 0. A cross-linked network polymer structure results in which sulfur bridges link the polymeric natural rubber chains. If vulcanization is allowed to continue until considerably more sulfur has combined with the natural rubber, a rigid, nonelastomeric plastic known as hard rubber or ebonite is formed.

The sulfur percentage, the percentage of other additives and the applied temperatures and duration during vulcanizing are the main variables that determine the technical properties of the hard rubber polysulfide elastomer. Thus there is a infinite variety of ebonite or hard rubber compounds, tweaked for specific characteristics. I think some high end bowling balls are made of ebonite, as are smoking pipe stems and other things. Here is an interesting article about old french mouthpieces with some information about the hard rubber used.
