I have tried a couple of crystal/glass mouthpieces recently. As many others have said before, the quality control is rarely a strong point with these, because of the inherent flaws in the production process. While the material is cooling down, the important internal dimensions usually deform.
I know machining glass can be a major technological challenge, because the material is extremely brittle. But in theory, it would be possible to create glass mouthpieces with smaller internals than the target measurements and finish the bore, throat, baffle and the facing with high precision CNC. I think this concept would worth the investigation.
Is there anybody who has tried to machine glass like this? It would be interesting to hear comments from mouthpiece makers or anybody who has some engineering background.

If a high RPM is used with high quality diamond cutters and is adequately cooled during the process as well as going gently on the material while cutting it by removing as little material with each passing, it should be achievable.

Easier to just buy Pomarico crystal MPCs. Probably a lot less expensive too.

Sure, it's easier, but my post is about an alternative glass manufacturing/finishing process and it's completely theoretical.

There would probably be a market for a glass mouthpiece that is made with high accuracy. Consistency seems to be a big problem for the glass pieces.
