Funny. I read this just after sorting slags for, I think somewhere short of a thousand times. I always 'see' things differently the next time around. I almost always find something interesting in there if I let time get in the way between sorts. This time, I had just extracted another little Pelt slag in great condition (back lit it is as yellow as I can get them to go). Missed it the first 999 times around, as I often do, because either I didn't have the right light, or the right frame of mind or the right angle or was distracted by work/phone/news/music/fatigue (called marble brain around here) or something. I'm the sort of collector that sorts and sorts again, and shakes it all down, and gets rid of marbles I don't want eventually...but not until I am sure sure sure the sort is done. Even then, you know I've missed stuff, passed on things previously, and found some real oddballs that way. Oh, the ones that got away...
