I mixed it in a PET bottle (filled with cold water and added FeCl with a
funnel) and the heating wasn't bad. Splashing was not a problem in the
bottle. You can do it near a sink then you could put the bottle in a cold
water bath should it get too hot. The thing to remember is start out with
what the label suggests on water, no less. If you think you'll add some
water later you'll potentially have too much ferric chloride and not
enough water, and it could overheat.
As for eye protection, i found i much prefer a face shield over goggles.
Not so much of a difference with chemicals, as i never had an accident,
but when sawing etc. somehow the chips always find their way round the
goggles into my eyes. (Even have burnmarks on the EYE-SIDE of optical
glasses over which i wore ALLROUND CLOSED safety goggles when using the
angle grinder)
Dunno but those goggles do not seem to fit my face ;-)... hmmm maybe i
ought to try a diving mask!
Anyway, the face shield is much better protection and visibility, and it
was expensive so i make damn sure i avoid scratching it... wish they were
more popular here so i could get them replacement plastic sheets in the
shops.
