kinda funny how the 44's have changed, from the 04's to 05's. they have been degakked, they no longer have povidone.
as for the slimy redness, if not completely deredded, i've heard that the redness will fall out between 95-100°, following "straight to E"- Post 440177 (https://www.thevespiary.org/talk/index.php?topic=8315.msg44017700#msg44017700)
(VideoEditor: "New Straight to E -- a novel extraction tech.", Stimulants) to the letter. it sticks to the glassware nicely at this point and the solution is poured out fast, into another flask that goes right back on the burner. it is obvious when the gunk has all come out, the solution is colorless. once the solution starts to become cloudy white with pfed, its too late.
right after all the red gunk comes out, the pfed does. so if the flask is not changed and the pfed falls on the gunk, well then you've got gunk in your pfed, and the gunk no longer sticks to the flask, it sticks to the pfed. touchy gunk with no margin for error, but with care, it can be dealt with.
