As compared to regular hard rubber ?
I've heard that they've stopped making eburnated rubber because the process is so toxic.
I know that regular hard rubber (or ebonite) is vulcanised rubber, it's made by adding 30 or 40% sulfur to the mix and that sometimes ground glass and ebony wood powder is added.
I believe that the famous steel ebonite mpcs contained a bit more glass powder than usual.
