Jdurg, thanks for you compliments and the warm welcome!
Please don't bother to clean all the pictures up, I've made some in good ol' sunlight.
They are below, the photo was made after work, in a Dutch summer/autumn sun, around 5pm.
It isn't too sharp, but the colours are much better, though the oil has also already a bit of a yellowish shine.
Unfortunatly I do not have a special vacuum bottle, however, I could make some very dry oil/solvent with anhydr. MgSO4, filter, add in a 100ml RBF, add potassium chunks, pull vacuum, release, gently not creating bubbles, flush all the oxgen out of the above air layer (I have an aerosol can therefore), and stopper it. Maybe that is a way forward.
The pieces with orange are indeed applying for a single trip to a large amount of water. Is a nice project, and íf I do it, I will try to catch it on tape and post it if anybody is interested...
Ok, the pic, here it is:
I know I can't do anything with the potassium, but it just doesn't feel good to chuck it all away, but maybe it is the best option.
BUT, if you think of the peroxidised parts of it, if it reacts under a few cm of oil with the K, and there are signs of fire, like a spark or something, to which extend would that be dangerous? The oil is plain parrafin, and cannot burn without oxygen, so there is simply no other oxygen there than is present in the K2O2 form... so under a large layer of oil, (I say large, I mean large, something like 10-15cm in a 600ml beaker) it should be able to abuse the chunks severely without any harmfull consequense for the experiment executioner, shouldn't it?
what do you think? It is handy nor easy to cut with a long knife under a large layer of oil, with a breaking index which is probably going to make you seesick, but I have done worse things...
