Hi ..
SWIM was doing an Extraction on Watcha-Tek, and collected all pulls in 1 container..
Then did y sodium-carbonate wash, twice and filles in 3 Glas dishes...
After freeze-precip, One had a bit fairly light yellow-colored
and the other 2 you can see on the Photo...
It was pulled with Zipo-Lighter Fluid.
ok, if those wheredifferent pulls , i could understand.
But coming out of the same collection container, (5 pulls alltogether) he wouldnt have expected not 2 totally different looking products.

ImageShack.usAnd why, although he washed the solvent twice with Sodium-carbonate and once with cold water, did this again and pput then in the freezer..
Why is it that Red-outcome... not even a single white chrystal shows up..
He is a bit scared of doing a Re-X, because he only has some naphtha left, and no heptan, bestine.
Last Re-X he tried with naphtha is in the freezer for 9 days now, and it doesnt chrystallize at all..
freezer has -28°C, which should work well...
where does all the red come from. As i said, no Xylene, or toluene used for pulling
Anybody got an advice for SWIM????
he ordered some bestine now from the states, because he couldnt find any to buy in Germany..
so before starting dong a new re-x, he neeeds to wait at least 14 days for delivery which is quite long...
Isn't here someone who could give advice..???
