I think you're being way too pedantic about what I wrote.

In any case, beli'ah could never be guaranteed to be zero. Knowing for sure
not even one cell remains from the meat that was last in the pot??? So yeah,
we really are talking about getting the beli'ah down to ignorable levels,
even in lekhat-chilah cases.

(Nosein ta'am lifgam is usable lechat-khilah, AFAIK. But I threw that in
as a tangent.)

As I wrote, I think that the flatness of the metal, even on a level one
can't see (but perhaps feel as more or less "sleek") has more to do with
beli'ah today than what metal the pot is made from. How they're washed,
or anything else we raised.

Soap, by extracting lipids / fatty acids / whatever they're called, from
those tiny imperfections could be the difference as to whether or not
the amount of remaining food particles is ignorable.

Gut Voch!
