Winterized BHO didn't turn out?

So this is the first run and I thought I did all my research but must have messed up somewhere along the way.
I ran about a 1/2 o through a glass tube and natural coffee filters until it ran clear into a hot water bath @ 115-120 for about 45 minutes. There wasn't any noticeable reaction left.
Scraped and dissolved into 190 everclear and froze for 48 hours.
After freeze strained it through natural filter in freezer and put in vac at @ 100F @ -29. Vac setup is a pyrex dish in ss chamber on heating pad. Temp gauged with a laser thermometer.
Left in vac for about an hour and a half, no noticeable reaction, scraped it and some of it turned to shatter and some was still gooey. It looked like the see through pic.

Put it back into the vac @ 100F @ -29 and couldn't get the reaction to stop. It was late and I got impatient so took it off the heat mat (crappy heat mat couldn't get the oil temp more than 100F, new one coming) and put the chamber on a griddle and turned the heat up a little. I couldn't accurately control it as easily on the griddle but it was as high as 150F as one point. After about 20-30 mins on the higher heat the reaction was no more but it seems to have sort of waxed on me. It now looks like the pic on the parchment.

It has a taffy like consistency. It smells good, and I took a small dab of it and it tastes fine but if you take a lighter to it, it sparks a bunch after it starts melting. Do I still have ethanol in it? Butane?

Am I correct in understanding that the Butane is removed in the winterizing process and when purging an absolute that's been strained it's just the ethanol you are evaporating, or is their still butane?

most likely no butane left over. just ethanol.. and maybe some water moisture .

accumulate into a goop, then re vacuum it with what ever low heat you got.. most the big bubbles should be gone when you are finished..

So I purged it again tonight until no reaction. It cleared up quite a bit and is a flexible amber near shatter at room temp. Did a small dab. Think it may have gone too long or hot cause a lot of the flavor is gone now. Seems to do the job though.

Still sparks some if you take a flame too it though? Is that even a legit test to see if there is residuals? Dunno. It's only like a g worth I've been trying to do at a time, so I feel it has to be purged.

The sparks you are seeing are moisture. I personnally dont like blowing directly into a warm dish causes condensation.

The butane is long gone and it sounds like you have water and maybe some alcohol. Easy to tell on the alcohol, because you can taste its sweetness when you vaporize it and water will cause an erratic fire dance when you combust the oil with a flame. Shooting stars, without firedance, is usually something solid like residual wax.

You've used too much heat at times, so you are unlikely to get shatter.

I get my best results by getting the puddle hot enough to be a liquid, so that the solvent molecules, racing around madly at those temperatures, can break the surface and escape, and about -29.5" Hg in a thin film until the solvent bubbles cease and only CO2 bubbles remain. I then just set it out and let it cool and harden.

Thanks for the help guys! It sounds like my biggest issue this time was with my heat and heat sources. My new mat should be here today so that should be fixed. I also think I may have used too much alcohol which I'm guessing could have contributed to my longer purge times. I'll be doing a couple runs this weekend and I'll let ya guys know what happens!

Also it seems that the flame/spark test isn't reliable then, as it doesn't necessarily indicate residual solvent?

The spark test is just a base. The more runs you make the more you will be able to tell if purged all the way. Taste and smell are good indicators

A little late, but our next runs seemed to turn out much better! My only question is; I have what looks to be no more solvent reaction and believe I have to be done purging but still not getting a total shatter all of the time. My temps are around 115-125 under vac.
