Thanks for the additional comments gang.
Regarding handling ether at low temps - just so folks are aware - or any other liquid that evaporates quickly can cause frost bite if spilled on the hands. The cold liquid not only steal warmth from the skin immediately but the evaporation also has the effect of cooling the skin below the ambient air temperature!
(I use gasoline for cleaning some particularly dirty mechanical parts. The gasoline is stored in an old fridge (not plugged in) on the north side of the shop and I have a small bench outside specifically for parts cleaning. I learned the hard way how fast liquid at -30 can steal heat from your hands!)
I don't know how it will work out but I intend to wear gloves while handling wet plate chemicals (as much as possible). I hope to avoid the discoloured fingers! I'll also wear gloves to avoid transferring the chemicals to my clothing, etc. (and my cigarettes!)
Mike: It's good to know that labs aren't worried about peroxide formation until the ether has been un-corked for 1 year. Us amateurs should be safe if we allow 6 months before disposing of any unused ether.
Very interesting thread - thank you all!
