Alex,
Thanks for the advice.
Whenever I do a "transfer", I do it within a basin,
so any slight spillage or splash stays in basin. If there is a drop or
two of splash, then it easily pours right back into
jug.
It has been many years since I've worked or played
with mercury. Modern parents would be appalled, but Hg was around
when I was a kid. We would "poke" it; chase it like marbles etc. Because of
Hg's "self attraction " (I don't know what else to call it), I've
found that a carefully poured thin stream quickly and easily goes right back
into the funnel and jug. There is virtually not a tiny drop of loss.
Must have a steady hand!
Here in USA, I've been told electricians or
plumbers are supposed to confiscate old mercury switches/thermostats. A
friend told me that he and his friends (when they were kids in the 1950s) would
collect the old switches for the Hg content. Just don't breath the
vapors!
Interesting stuff.
Bruce

Bruce, Be very careful with mercury. If you spill it on the floor or on the ground when filling or emptying the horizon basin, it may cost you a lot to clean. Alex. > When warmer, some starry night I'll try this out and compare results > against a mirror. > > Bruce
