    Re: greenstone mouthpiece?

    I've not made a mouthpiece from stone, but I've done a fair amount of mouthpiece work. Is the consistency of the stone rather homogeneous? I think this is the most critical factor as to whether it can work or not. If it is layered or composite in nature, you may have a difficult time achieving a smooth surface, or you may need to apply a thin layer of epoxy to some parts of the inside to smooth out small pits and holes - particularly near the tip. Also, you have to consider the thickness and strength of the rails and chamber walls. Material that is strong when solid isn't necessarily strong once it's been hollowed out. All it will take is a vein of weak material in the rock and the mouthpiece could collapse under ligature pressure or stress while being played. "The guy was playing low Bb so loud his mouthpiece exploded..." I admire your taking on the challenge, though I recommend you monkey with some practice pieces before you take on this formidable project.

      ok insted of going all out and making the whole thing in stone (which would be pretty hot) what about making parts in stone and parts with hard rubber or metal?

        I have an old Holton mpc which has a metal chamber and facing and a hard rubber shell that makes up the upper body of the mouthpiece. HR comfort with metal performance. Not a bad idea, though the price given modern manufacturing practices would be rather high. Granite runs about one third the density of brass, so I'd guess the stone piece would play more like a plastic mouthpiece than a metal one, if dimensionally identical. How about taking a base mouthpiece and adorning it with stone? You could achieve a unique appearance, yet still have something that plays.
