1300.0. "Must I throw this pan away?" by CTCADM::THOMAS () Fri Jul 29 1988 18:12

    We have a skillet which my wife says is a "Silverstone". It's got
    a few scratches on it, and she says now that it will have to be
    thrown away, otherwise we'll be poisoned or something.
    
    I've never heard anything like this before. It's been scratched
    for more than a year now and we're still alive (at least, I think
    so).
    
    Can anyone enlighten me on this?

1300.1I wouldn't worry about itBEING::SCHOELLERSat Jul 30 1988 17:2718
    I am not sure on this so don't quote me on it.  I believe that small
    chips of Silverstone are not poisonous.  Therefore, you can still
    eat food that has been cooked in a scratched Silverstone pan.  HOWEVER,
    Silverstone (I am not sure but this may apply to other non-stick
    cookware), when left on a hot burner with no food or water in it
    (i.e.   letting the water boil away accidentally) will give off
    toxic fumes when the pan becomes hot enough.  I believe that I got
    this little tid-bit of information from a TV show such as 20/20
    or something along those lines.  Somebody did let some water boil
    away in the pan and the fumes killed their pet bird or something.
    Sorry for being so vague.

p.s.
    I have cooked from a scratched Silverstone skillet for about 5 years
    and nothing has happened to me.....me....<cough>....<choke><choke>...

1300.2NOT GOOD FOR YOU, BUT NOT OVERTLY POISONOUSBENTLY::WILDETime and Tide wait for NormanMon Aug 01 1988 21:117
It is not GOOD for you to eat the little fragments of silverstone coating
that gets into food from a damaged pan, but it is not overtly poisonous
to use one.  The coating is made of chemicals you wouldn't ordinarily
eat, after all.  Figure it this way, the pan was less than $10 or $15
and your mate is concerned about it..... 8^}

1300.4Got them ol' Teflon blues again, Mama...FGVAXZ::RITZIt's life and life only...Wed Aug 03 1988 15:1817

	 I believe SilverStone coatings are made primarily of Teflon, which
    is   the   DuPont   trade  name  for  carbon  tetrafluoride.   At  high
    temperatures,  (>400  F) a reaction take place and caustic fluorine gas
    can be released; unless you get a snoutful, you're probably OK.  As far
    as eating it, your guess is as good as anyone else's.  Certainly we eat
    small  amounts of fluorine all the time, (my natural bodily fluids have
    not  yet  been  perverted 8^) ) but the long- and short-term effects of
    ingesting  carbon  tetrafluoride are, to my knowledge, largely unknown.
    A  similar compound, carbon tetrachloride, is a known potent carcinogen
    and teratogen.

	 You bet  your  life  (or  in  this case, someone else is doing the
    betting...)

1300.6ENAMEL COATED PANSREMILL::PUSHORWed Oct 19 1988 15:066
    
    She may be thinking of the old enamel coated pans. If any food
    containing citric acid was cooked in them under the described
    conditions, then supposedly, there was the possibility of negative
    side effects.

(I know it's been years since it was posted, but I just happened to run
 it . . . )

There's always the chance that it will react to form a flouride which will
strengthen your tooth enamel! :^)
