[UPDATE]Found these pics of a freeze-precip--w/big crystals!

Migrated topic.

So I thought I'd post them and ask some questions based off of them. [img:db99c12647]http://img264.imageshack.us/img264/4700/spicefreeze001zh4.th.jpg[/img:db99c12647] [img:db99c12647]http://img123.imageshack.us/img123/6933/spicefreeze002cz7.th.jpg[/img:db99c12647] I'm guessing the solvent (looks like Bestine tin on glass in pic 2) was evaporated down substantially before being put in the shot glasses, and was then heated to super-absorb the spice forming in the bottom of the evap. container. Then, placed in the shot glass and freezer, this is what happened. The impurities and small bit of yellow/brown waxy sludge appears to be separate from the white spice crystals. ---------------------------------------- NOW FOR THE REST OF THE STORY... what did this person do next? The story ends there-- with no impression of the next steps taken. Is this the stage where you remove the glass, and pour it through a coffee filter immediately, and harvest clean spice? Is this the "final stage" ? Or was this just an initial stage of good refinement... Any help and comment would be instructive :) (PS-- what a wonderful forum! )

Some new info was just received-- it appears that the third, failed OMS pull was air evapped after no CFC precipitation was successful. A gooey, oily brown substance remained, that has the aroma of a certain spice. [img:e93ece55b1]http://img182.imageshack.us/img182/5796/omspullresultshz5.th.jpg[/img:e93ece55b1] The objective observer didn't know why this would happen with OMS but not Bestine, or VM&P Naphtha, and neither did the Texan, who was CFC'ing the VM&P (Fifth pull) successfully with large, white crystals as of the time the Texan was posting their message. If there was a way to somehow convert this weird sludge into crystal, what could it be? The Texan stated that upon collection and "drying" of the oily goo, Bestine was added to the small jar containing it, and heated by hot tap water to see if it would absorb into the solvent, allowing for precip... but the contents did not appear to dissolve the goo, even after 120 degree heating and agitation, and the Bestine was placed into a separate container, CFC'd, and shown to produce slightly cloudy haze, but no discernible spice.

Wow, that bark the Texan is using just keeps on giving, huh? Cool. Looks like the OMS pulls spice just fine, it's just no good for freeze preciping. Actually looks like it pulls a little too well - tho maybe that's from the heating. All that gunk could have kept it from precipitating too. How much is there - relative to the bestine and naptha pulls? Would be interesting to find out what would happen if half was washed in bestine and half in naptha. See what doesn't dissolve and what evaps out of the solvent. Pretty please? :lol:

I implied from the note I read that it was impossible to accurately measure the goo because of equipment/tools that were available to her. The jar pictured was a 1/2 pint jar, to put things in perspective. The jar had Bestine poured into it to see if it would absorb spice out of the goo, as mentioned above, then, after being allowed to completely dry of Bestine (that went into it's own jar) , the above pic was taken. THEN, VM&P Naptha was poured into the jar, sealed, and heated externally with tap water. Again, no visible absorption occurred, but the Naptha that was exposed to the goo (which was still sticking gooily to the small collection jar), was placed into it's own small jar and CFC was initiated, with no further results found on the internet. One would assume that the Texan had, at the time of the intercepted writing, two 1/2 pint jars in a freezer, both having been exposed to the goo, allowing an eventual side-by-side comparison of what, if anything, was being pulled from the goo into the requisite solvent.

I found a message from an unknown Texan indicating that there appeared to be some spice present in BOTH of the two solvents that were poured into the goo jar and heated. There was evidently a ratio very similar to the earlier pictured examples-- a small single blotch of whitish crystal in the OMS, and quite a few tiny, more "traditional" crystals on the bottom and sides of the Bestine jar. There was mention that the jar containing Bestine had a bit of debris/lint/dust from the goo that had been blown into the flat dish that the OMS was originally evapped from, and that the debris made it difficult to accurately gauge the amount of legitimate spice present... but this mixture would eventually be heated to re-liquefy the spice, and filtered through a coffee paper while warm to remove the dust and debris, and would then be re-CFC'd to get the unencumbered crystal. *** Very interesting, seeing as it didn't at all look like there was any absorption/dissolving of the goo-sludge from the bottom occurring. It appears that there is in fact some spice present in the goo, and probably still more locked into the gummy sludge, seeing as what is viewable now had to have been leeched from only surface contact with the goo, since it didn't appear to dissolve at all... A post-script mentioned that a sixth--and probably final-- pull: a quart of Bestine-- was introduced into the lye solution gallon, where it would be heated externally with tap water only, and removed after an hour of exposure. Just to see. The conclusion, thus far, appears to be that Bestine is in fact best, producing extremely clean, high-quality spice, with almost no taste at all when smoked... and that VM&P Naptha does in fact do a far superior job as compared to OMS-- at least in this case, and under these documented conditions-- very close to the Bestine... (though one can't be sure that it's not truly as good as the heptane as these pulls were not equal /sequential ) To review: 1st and second pull: Bestine 3rd: OMS Fourth: Bestine Fifth: VM&P Sixth: Bestine There were no further updates I could find...

Hmmm... I was just informed that the sixth pull got something... but it's like nothing seen before... It's white, and flake-ish/wispy, floating throughout the solvent-- almost like some kind of sediment, which settles to the bottom when undisturbed but floats when stirred... certainly nothing like the crystalline substance known to be spice... Weird... It was to be CFC'd to see what happens to it... :confused:
