TEK - coke not drying up fully after acetone wash

[kip]

Hi,

the last couple of times swim has done an acetone wash, but the stuff isnt drying as well as it was before? swim does keep it in small chunks while drying and breaks them up too again and again because it doesnt dry fully, it stays a bit gummy.

before swim used to just wash it, than squeeze and let it dry all in chunks and it looked beautiful, but now its all weird and looks like pieces of gum.

Is there another drying method?

Currently swim is just taking the stuff after acetone wash, and squeezing it through filter onto paper towel, than leaving it under a warm/med. hot lamp for 10-20minutes. swim has even let it sit out for over 12+ hours and still didnt dry up fully and cant even crush up to fine powder.

Thanks for any help!
