I had to sand a brass bushing to gets its diameter down a little bit,
a few days ago. Produced a lot of fine dust. I may have been careless
and put some food item in my mouth with dirty hands. Ever since, I
have slightly bitter taste in my mouth whenever I eat literally
anything. The bitterness reminds me of the taste of oak acorns or some
such. Does it make sense to link this to brass sanding? Other than the
bitter taste, I feel fine.
You aren't supposed to eat acorns :-). I think they're poisonous.
But I just tried putting a piece of freshly cut brass in my mouth and it
didn't taste of anything. Brass isn't very reactive. Personally I doubt
it's the brass. Even if it was responsible for the funny taste, I would
have expected it to have cleared after a few days.
Just had another thought. I remember my father (who is a dentist) saying
that putting aluminium in your mouth can cause pain if you have
fillings. Apparently it's some kind of galvanic effect. But aluminium is
more reactive than brass, and it's also unlikely that such an effect
would last for several days. It would only happen when you put food in
your mouth if the food caused the metal to be released into your saliva.
On the whole I think it's unlikely that the brass dust is the cause of
I've had this taste from copper dust. It lasted for a few days. And my
tongue felt strange. I guess you need to be more careful. I also got a
slight case of metal fume fever from welding on zinc plated steel
years ago. I now pay close attention to what I breathe and eat.
Not sure about that, but they are very bitter. Supposedly, if you soak
them in water for several days, you can cook and eat them. Never tried
Could have been different if it was brass dust (not that I am asking
you to try).
I hope that it is actually clearing.
Odd... I've always had a very sweet taste after making chips or filings
from coper-containing stock - Particularly if I take a hit off a
cigarette - Seems like something in the coper-bearing stuff interacts
with the cigarette smoke, and like I just dumped a spoonful of sugar in
my mouth, only without the texture. It often persists for days,
particularly if I've made lots of *REALLY* small (AKA dust)
At one point earlier in my life, I tested the theory that it was
something to do with copper and got what I consider pretty solid
confirmation - The procedure: strip a piece of 3/12 romex, and snip off
a few small pieces of nice copper wire. Roll them around the mouth for a
few seconds, spit 'em out, then take a hit off a smoke. The results were
impressive - As soon as I drew on the cigarette, it was exactly as if
I'd taken a mouthful of corn syrup - my mouth was filled with a thick,
super-sweet taste that nothing would "rinse away". The effect persisted,
although gradually decreasing, for several days, seemingly being
"reactivated" every time I took a drag off a butt.
Maybe the question of bitter vs sweet is an "individual chemistry" thing?
As far as health concerns, copper is one of the "trace nutrients" we
need, although I imagine when you've snarfed enough to taste it, you've
had the daily quota and then some for several people. Excess copper *IS*
toxic to sheep - A fact that's noted on animal mineral-salt blocks.
But to humans? Dunno... I'd imagine the LD50 is up there fairly
So, you won't be needing that die grinder and those welding clamps,
then? ;) (looked for the grinder last night, I now know two places
where it is not. Found the clamps, though.)

That item is CDA 932 bronze, leaded. Might be SAE 660. John, what
specifically do you see about that that I haven't found yet that says to
seek medical attention? He's got to know what to tell 'em to look for.
All I've found so far is lead.
