here’s some highlights…with links back to the threads they came up in.
I liked the boiling Iso approach 
edit: unfortunately that icmag link doesn’t work at this point 
the thermos trick was one I learned from the @SkunkyFarmers, and the only time I’ve bothered using butane on kief.
chances are the input wasn’t much better than yours.
winterizing it would probably have helped given the 8-10hr soak at -2 or 3C.
processing similar material (“kief” from machine trimmer) with ethanol was never a favorite either.
