Ya Marcia,
Charcoal Briquettes are full of wierd junk, plenty of
'metal' shreds in them...seems like mostly Steel. Likely
from nails, staples and the like I'd guess...from whatever
re-cycled scrap or disuse they shred to make the Briquettes
out of.
The old ones did not have these inclusions.
I heard once, ("Kingsford"?) that the 'Charcoal Briquette'
was the invention of Henry Ford, who wished to make a useful
product of the scrap and cut-offs of the (mostly 'Ash' and
some 'Poplar') Wood used in Automobile construction ( in
the Body as well as for tack-strips for the interior
upholdstry...) but likely used whatever other Wood from
Crates and Shipping dunnage as they otherwise acculumated as
well, I'd imagine.
The Ford Motor Company in those days owned their own
Forrests for the Body and interior Woods...and much else
too...owned the Iron Mines ( where, Ore as was mined one
day, was two days later an Engine block for the Model "T",
the Barges and Ships, the land as had the Sand and Silica
for the Glass to be made of, and the factories as made the
Glass...on and on and on...

the oils are contaminated and/or duleted with many
chemicals and "metallic substances". Else why do you change
your oil as the oil filter removes the particles - just
change the filter. Seems like even if you burn it, you would
have some toxic residue. In fact, I really don't know what
is done with the used oil except it is "recycled". As a one
time drag racer, we changed oil each 1/4 mile run on the
funnycar we owned as the exotic fuels we ran, such as
nitromenthane, propaline oxide and hydrozene would turn oil
from amber/clear to a solid green color in only one run.
and the oil would be very different texture. Multiply that
