If you just read this, it is proof of my belief, that old threads are still valuable/interesting and worthy of commenting about and /or responding to. PS. in tightly sealed, stored in a dark and cool place and in fully filled, glass bottles, never opened, the oil stays honey colored, maybe, about a year(longer ,I don't know about) , from my experience, so it could be simple oxidation or light exposure. Perhaps a CO2 flush before sealing is called for?
Thanks for jumping in my friend.
exactly...the colder the better. 99% USP iso* or nothing...every other iso has chemical blended into it. filtering is important too. i run it through coffee filters three times and let it sit in the sun or in the grow room in clear jugs for a couple three hours. it turns from a hint of green to a nice honey color. the light strips the chlorophyll. not burning it and getting 100% of the iso and water out is important. i use a digital hot plate to evap 99% of the solution off on a glass pie plate...it never burns this way. i let my final bit of solution sit in a mini crock pot { presidents choice with the glass lid and blue light works the best...dont ask how i found this out. lol } in a stainless cup floating in veg oil like a double boiler. it sits exactly at 220 degrees for 3-4 hours to get all the iso and water out. once i see zero bubbles i let it sit for another hour. then suck it up into a glass syringe and squirt it into 5 gram jugs. it looks like golden corn syrup when im done. i only let my bud sit in the freezing iso for 3 mins. then wash it again never taking anything out of the freezer till all the solution is wrung out of the buds. i even found a wine press to squeeze out the iso trapped in the bud i couldnt get out before. the longer you let the bud sit in the iso the darker your solution will be. eons ago we used ether to strip it and got honey oil after going through activated charcoal like they make shatter these days with butane. speaking of butane you should do the mirror test if you use a diff brand. they put a small amount of oil in the butane can so it doesnt rust inside. my .02cents
Welcome, there are lots of write ups using cold to extract oil. even better if you live somewhere.
Pics after my Bud washing… harvest fresh plants…now I know my end product will be squeaky clean- vape anyone !!!My oil technique from article I read.
********
2 GREAT articles:
Super-Cooled QWET Wash for Cannabis Extraction Using Dry Ice
&
CANNABIS OIL QWET EXTRACTION BATTLE OF THE WASH: DRY ICE VS. FREEZER
My oil from -55f extraction with
Everclear alcohol & dryice with soak time extraction of 25 minutes. 1st filter used for expediting wash from herb is a 75u micron clean bubble hash bag filter &
2nd filter is a brown coffee filter
20-25u microns
Hot electric skillet for alcohol evaporation & coffee warmer for final oil concentration (removes any residual water alcohol is long gone).
For those of you who unaware
this super cold extraction technique removes about 30 to 33% of undesirables…such as
Chlorophyll, lipids, fats, waxes, & other undesirables…
I have proven this by doing it at room temperature and the cold technique— and weighing both end results before and after.
((I am also a firm believer in bud Washing and I do it before I make any extracts, I have found no difference in the end product, whether smoking it or not… vs NOT bud washing))
Been doing this for over 5 years.
Finish it off on my coffee warmer, stir until micro (residual water) bubbles disappear— alcohol is long gone !
((Note: Everclear has been repeatedly distilled to create a pure, clear, and unscented product))
Without going to a dispensary, it is the cleanest oil I can find and HELL I trust it I made it …!
