One More ISO question and

[OneLegUp]

Thanks to all who provided input/feedback on how to do an ISO wash...

Took my 18z of shake and 6 of air bud...and pressed it down in a 5 gal bucket... then took 10 bottles (160z) of 99% that had been in the freezer and dumped it over the green... 10 bottles barely covered the green.. I let it sit outside in the morning chill (50F) for about 20 minutes... then strained it.. through paint strainer bags, and cheeze cloth....

Dumped the liquid into a crock pot.... on low (liquid temps were on avg 120-125F) started the reduction... in 4 hours it was reduced in half... then it sat overnight... restarted the reduction until it was down to about a quart...

then I restrained the mix through coffee filters one more time to get the final fine particles out..

Back to slow reduction... to the point I could then put the 4 ounces of liquid into a glass pie dish... and placed it over hot water in the crock pot until it got down to a thick and a reddish amber color...

Now I noticed a small area that looks like what gas looks like on water..

Is that still remnants of ISO???

And how long should I let this sit to make sure all the ISO is gone?

Thanks to all...for the past input and answers if any to the most recent question(s)..

That is the oil, there is still ISO in it. When you are close take a pin head size blob and put it one a glass of cold water and see how thick it gets. You should be able make it stand up, like a Dairy Queen Ice cream cone, when it is done.

That "gas on water" looking stuff shouldnt be present. It sounds like you have a soap or petroleum contaminant. I've made a LOT of ISO/BHO and have never seen this.

The ISO evaporates fairly fast. it's the water that remains after a period of time. I wait till my stuff is hard before I scrape it. I usually use my gas oven @ 150*F for a bit to "bake off" the last bit's of water.

pharma...thanks

its.... butter

after reading your post... I kept thinking... no way a contaminate got into the mix... the crock pot was clean...the bucket etc... then I remembered I had used the one strainer (w/coffee filter) for straining cannabutter... and it obviously didn't get cleaned with hot water as well as first thought...

Well, there ya go. Another one of life's little mysteries solved. Chalk one up for the good guy's. Nice back-tracking Onelegup, that could of bugged you for days. imagine trying to evape butter off the puddle.

[PharmaPharmer]

Ah yes butter! Good deal. Much better than a petroleum contamination! I put some super premium BHO I made into a vial that I had not quite cleaned out all the way and it came out tasting like burgamon which was what the vial previously contained. Lesson learned and I can't stand that smell/taste anymore!

Thanks again Pharma..

another question if your don't mind...

I noticed the edge is very tough almost crysaline when scarpped with a razor blade...yet the base of the plate and bulk of the product is gooey...

Throughout the day I've had the glass plate sitting on a heating pad...to get rid of any other remnants of ISO... and note a sweet aroma emitted.......

oops my question.... is the crystaline/gooey situation normal??

[pflover]

yes it is normal.

you are not going to want to smoke that if it has butter in it. seriously. if i were you i would add more butter and make it into edibles. the same sorta mistake can happen if you leave seeds in the bud when making oil. the actual oil from the seeds is also extracted into the alcohol and remain in the hash oil. it is not only unpleasent to smoke such carbohydrates but not good for you lungs at all. you don't have to listen but that's my 2 cents.

[soulmate]

That crystall stuff is plant sugars. You will not get any effects from it and it will make your goo burn hotter. You should try and remove it from the goo.

i'm not sure i agree about the assessment of what the "crystaline" stuff is. regulare oil can dry out to the point of being "crystaline".

[PharmaPharmer]

I agree with PF. I've notices several different "fractions" of ISO oil during my expirements trying to seperate the tars and plant materials. I too have noticed that darker colored ring around the evaporation vessle. It does appear to have crystaline properties but I think it's actually just hard and flakey oil with less contaminant. In my runs the ring is always a darker red than the golden amber Oil. I've noticed that longer washes or too much time in filteration causes more of that stuff!

[pflover]

i can get crystaline stuff around the side or even in the center of ANY oil, iso or BHO, if it is let sit long enough. it is a factor of drying out more.
