That pot does have a pretty wild temp swing on quad cores.
Acetone = #1
99% Isopropyl Alcohol = #2
99% gelled up on me in that pot. Get acetone it is cheap and just make sure the windows are open when you bench.
Wrap a paper towel around the top of the pot (that insulation will sweat), and get a paper cup, cut the bottom out and stick it on top of the pot to prevent splashing

I was using styrofoam cups when I was using alcohol. that WILL NOT WORK with Acetone.
I tried making a funnel out of a piece of paper for the top... it did not work well enough IMHO. an 8-12oz cup should fit on it perfectly.
