Very interesting! One question though. When you said:

A base coat which was a polymer mix to adhere to the sand blasted and
etched pan surface, a second coat of PTFE with decorative speckles
(and/or pigments) and a clear over coat of translucent PTFE

This looks like it means the surface of Teflon cookware coating is
this "clear over coat" rather than the PTFE. So how does the extremely
low friction coefficient of the PTFE come into play if it's covered
with a "clear over coat"? Seems it would be the friction coefficient
of the "clear over coat" that would interface with the food products.
Plus how do they get this "clear over coat" to adhere to the PTFE, if
it's the PTFE that has the extremely low coeff. of friction? I know
it's hard to get paint to adhere to most plastics, of which PTFE is (a
plastic.)

Seems the original fundamental question still remains!
