Homebrew PCBs

About the FeCl chemistry, try the links section.
I sure have seen pages describing the reaction, but i don't have any URLS.
If it isn't in the links try google. Shouldn't be too hard to find.


Tinnit _could_ be containing thiourea, which is a known carcinogenic  
substance. Don't mess about with it and you should be fine. I don't use it  
for that reason (i try to avoid anything over Xi rating). If anyone has a  
msds on tinit let me know.

cool-amp seems to be non-hazardous, but more expensive. I think i'd like  
to try that one day.
