H'm. Sorry for shooting off my mouth. Computers (peecees, anyway...) I
know, but chem is not my cuppa tea.
That's ok, old warnings from the past are hard to get rid of. One
that I heard just tonight was "if you aren't careful when you make your
own booze you can go blind". This came from the era when alcohol was
prohibited, and some unsavory people would repackage denatured alcohol
(ethanol with a percentage of methanol in it to render it poisonous so if
you drink it you will either go blind, or die, thus prevent you from
getting pleasure from UNTAXED alcohol). After a while, they switched to
formula 19 (methyl isobutyl ketone I think) as the denaturant so you don't
go blind or die, but you _wish_ you were dead. To this day people think
you can go blind from homemade booze. :-/ Some stories never die.....sq
FWIW It wasn't just denatured alcohol that made you go blind. It was
the lead solder that some people used to solder the copper together to make
stills from. The old time moon shiners put copper stills together without
solder but during prohibition a lot of quickie stills were put together
with gobs of solder and the lead would leach out. Anyone here ever study
moon shining? Fasinating subject (except to Sam of course).
