Re: A load of cobblers?
- Hi All,
I have read that letting the product "fall" into the collection
vessel allows fusil oils to evaporate on the way down. It would seem
to me that, ethanol having a higher bp, fusil oils would be left
behind, a bit counterproductive, JMSO.

value your life/eyebrows you really should condense them. Highly
volatile vapours can be lethal. Some also have an annoying habit of
"creaping", whereby the are heavier than air and seep through doorways
undetected, until they reach an ignition source. PLEASE do not
