Walter,
thanks
I would just add two observations to my previous ones
about crystal. Because of extreme hardness and lack of
surface friction, facing super-cooled liquids i.e.
glass mouthpieces using similar hand control as with
rubber , starts to bite into making a curve at a
different angle and starts later. This is invariably
true no matter what abrasive technology is used. Often
the shorter facing resulting from this material is
round lapped into a more gentle start, increasing the
apparent facing length. We all know this is at least
as important as anything else.
Since the dimensions of rubber an crystal m.p.'s have
not ever been made close to same, the effect that the
material itself contributes has not been accurately
addressed, even with computer modeling and
spectrometry.
