swim did a few xylene pulls, after 3 naphta pulls..
he collected the Xylene in a Pyrex dish, and used FASA to get Fumarate chrystals.
a few day later he looked, and pipetted the xalen, and all that was leftover was a thick layer of brownish goo, which has hardedn now over the weeks.. see pic1

as he lit it with some fire to see if it will just liquidize, he was surprised, it really burned with a large Flame..? see vid..


as he has quite a lot of this, he is very interested in what this is, and how he can convert it to a smokeable Deemzter???
