I have some BHO that a friend gave me. I asked him if he purged it and he got all defensive as if I was implying that he did not create the oil properly. I just want to cook with it.
I was going to purge or heat treat the BHO myself as Madd_hatter described on the first page of this thread. Placing the glass jar in boiling water. Leave the lid on?
Is this a good idea? Another thing I have been reading about here that confuses me is "the blast". What is that? Do I need to do this also?
Please keep in mind that I am completely new at this. I have not created the BHO, nor have I used it before. I have been trying to research this on many forums and appreciate any help from those with experience.
Thank you
if you are planning to cook with the BHO, may i suggest while it is still liquid from repurging you infuse it to some Olive Oil.
Thanks for the reply. I have so found very little knowledge for noobs out there who want to start cooking with BHO. One thread I have on another site has sat for weeks with no reply. This is why I am going to start using this as my main site.
So, set up the jar with the BHO in boiling water. Can the jar just sit in the pan, or do I need to suspend it somehow so the bottom of the jar is not hitting the bottom of the pan? Does the water need to reach a certain temp? How will I know if I have purged enough to make the BHO edible?
Once the purge is done, how would I go about adding the olive oil? Is there a technique? I only have a few grams of the BHO for now, but I know there is plenty more available to me if I can just learn how to use it.
Thanks so much.
The problem with using Ethanol as a solvent as i see it, is availability.
Here in the states it is illegal to distill your own spirits...
just on a much larger scale, and with different solvents.
The use of different solvents is what I'm referring to when I say no chemist would use this method. I mean no chemist would use this solvent system--it is terrible for what the goal of this process is.
Realistically if we're talking getting pure THC, you're going to have to solubilize the THC--which requires changing its chemical structure. Then you would purify it using a sep funnel methodology as above. Then you'd reverse the process to give the oil.
Let me know if you have any questions on what I'm getting at, or how to set up a control experiment to test results.
Looks like this thread has wandered a bit, so I will stray some too.
We currently purge BHO under 29.9" hg vacuum, while keeping the pool molten around 120F using gutter heat cables wrapped around the bottom of the vessel.
We wash that out of the collection vessel with hot ethanol, and freeze that overnight to coagulate the waxes, which we filter out before evaporating away the alcohol by either distilling it off with heat, or in a thin film under 29.9" vacuum.
You may skip the first vac purge if you are using hot ethanol to extract the oil from the collection vessel. This step (with additional heating and stirring) will purge butane on its own as ive described in my previous post. (This is really the main help I was attempting to provide)
Sorry for the double quote, but it should also be noted that whatever butane will pull out--hexanes should pull it out better/faster (quicker time of elution). The only real question i have as to whether or not hexanes will be better is if terpenes are water solubule--common knowledge would have to tell me that they most likely are not, though. This really brings up the utility of having a liquid solvent if it is the case. If its pure terpenes and cannabinoids you're after then you will not get closer than you currently are without washes in some kind of sep funnel.
Thank you for your sage advice SQ!
That is in fact how we used to make ours, until we developed the ability to do a hard vacuum purge at low temperatures for both butane and ethanol.
As you note, no butane was ever detected in any of our oils after simply boiling off the alcohol, so we are perhaps gilding-the-lily, but not everyone wants decarboxylated medications, so we also developed cold boiling processes.
