Does anybody else heat theirs up when they do the extraction? or can anybody provide some insight.
Baffald said:First pull of clear naptha did not produce any, the 2nd pull with clear produced and everyone thereafter has so far. Was busy for a few days and left pull # 6 sit and just extracted and placed in the freezer.
Next will be pulls with xylene. Will the "jungle" freeze out as well?
Baffald said:I did not defat with straight naptha first. I will do that next time with the MHRB and see if the yellow is due to fats and oils. Seems my first pulls and jars formed white crystals but as I continue each batch is getting more yellow. I think its due to the break down of the bark.

I have tried a dry defat and it didn't make much difference to the end product IMO. I put enough warm naphtha through the bark, thinking i would be left with a really clean product, but i had the same off white crystals i usually get after freezing. There are easier and more efficient ways of getting a cleaner end product. I still think recrystallizing is the way to go, but then again i haven't tried all the defat techniques that are out there.
It depends on where you live. In the UK I think it's sold as 'Bestine' and I've also heard of the name 'Powerfuel'. In some european countries it's called "chemically pure gasoline" or something alike. It really differs, but the main purpose is fuel/cleaning/inkremover. Look for such products and check what's really in it. I've never heard of heptane sold as heptane so to speak, you have to check on the container (look for 'n-heptane').Baffald said:so where does one get heptane? any type of hardware or craft store? or is it something i need to get over the internet?
