I you fry pot stickers in a non-stick pot, what happens?

always most valuable when he had lost it.

The pan does usually win. BUT, if you put the pan on a low heat without oil and cover the pan with the lid, it won\'t stick. For example. you can cook chicken breast in a non-stick pan at a low heat without the chicken burning or sticking to the pan. Issue only comes up when you put the pan on a high heat without oil.

How do non-stick coatings stick to non-stick pans?

The pan material has to be clean and chemically more active than
you generally find in nice metals. So, you rub the aluminum pan with sodium.
Then the PTFE sticks to that surface.
I think that the sodium then reacts with the adjacent Teflon, pulling
the fluorine atoms off the Teflon polymer, yielding something that
will stick to clean aluminum.

This comes from what I saw at RCA in the 1960s, where Teflon-insulated
hookup wire was treated using metallic sodium dissolved in some kind
of non-aqueous solvent. Also treated Teflon tubing intended to be
slipped over solid wire that way. The white Teflon insulation turned
light brown, and urethane conformal coat and the like would now stick
to the wire or tubing.

I used to use \"Tetra-Etch\" for such purposes. It is an organo-sodium
compound. Another way of achieving a similar result is to heat the
surface very briefly with a hot flame (with good ventilation).

I think that\'s what I saw used, back in the day.

This is very dangerous. The smoke is quite toxic. Do outside, with a
positive-pressure supplied-air mask.
