Why do metal utensils not scratch it?

• fluidcruft 11y ago
  I think what was meant (and that I can anecdotally confirm) is that metal utensils do a much better job of stopping what I will call "gunk film overgrowth" during cooking.

  It's not that metal can't scratch it; it's that NON-stick surfaces are highly vulnerable to being scratched by metal, whereas cast iron is much, much less so, and scratches can heal as long as you cook with more oil.

  Iron is a harder metal than 'steel'.
  • elektromekatron 11y ago
    Not true. Steel is about 5.5 - 6.3 and Iron is around 4.5 on Moh's Hardness Scale. Higher numbers are harder.

  They do scratch it, that's why they keep it smooth, but the iron is not a coating and is non-toxic, so it doesn't matter about wear.
