Yamaha ebonite mouthpieces are formed from natural materials Mouthpieces are manufactured through a traditional process.
Natural rubber is the raw material for ebonite.
Sulfur is added and then mixed with the rubber, after which it is baked in a kiln. Yamaha starts by selecting the best raw materials for making mouthpieces. The temperature of the kiln is precisely controlled. We use proprietary know-how to thoroughly heat and temper our mouthpieces. Next each mouthpiece is carefully finished using a high precision polisher.
