propylene glycol based tincture
Do not use iso for this, ethanol alcohol only. I use everclear, some folks have used 151 and vodka with success.
Try this, it's known as a propylene glycol based tincture. Mixing vegetable glycerine and ethanol (everclear) will give you propylene glycol, a known food additive. I also add distilled water and Loran propylene glycol based flavors (hard candy flavoring) to the hash. Good stuff for sure and potent.
I like to use the bubble bags to make hash out of the MJ, making sure to press all the water out. I find it's easier to measure how much is going into the tincture. I have also found that one quarter of some good stuff is about 1 gram of hash when ran through the bags. I use 2parts glycerine to 1part distilled water to 1part everclear as the base.
If not able to use bags, then convert the bud to hash using the green dragon method, again using the 1 quarter ounce to 1gram of hash conversion, not as accurate as bubble bags but not too far off. One plus is you won't have to mix it as much to break down the trichs by using the green dragon method of extraction. Boil off as much of the everclear needed to get the right mixture.
If I use one gram of hash, it gives me two one ounce bottles of tincture, just multiply using the formula if you have more bud or hash to make tincture with. I like that I can make it in small amounts if necessary. I have seen others use one gram of hash for a one ounce bottle of tincture but prefer two bottles tincture.
I start by putting the hash in the oven at 300*F for ten minutes to decarboxylate and then add it to two ounces of the ever clear to break it down. I shake it in a canning jar with a wire whisk ball inside to help break down the hash, which usually takes a few hours of good shaking.
I then reduce the everclear by boiling most of it off in a hot water bath (use much caution, research it if you're not familiar with this, it's easy just be safe and again, research) to one half ounce and add one half ounce of distilled water and one ounce of vegetable glycerine. I then shake it well and add it to my little dropper bottles. I also started adding the Loran flavorings, good stuff, I like the pomegranite and watermelon. I add about 4 drops of flavoring to 1 ounce bottle of tincture.
If you find it's too much alcohol, you can boil off more on the next batch. My brother mixes different oils in his, like pinon nut oil as of late.:hi
Excellent to use sublingually and the flavorings make a huge difference. My wife uses it for migrains, usually one half of a dropper is good for her, 15ml I believe.
My brother uses the atomizer spray bottle, I prefer the dropper but sometimes use the spray bottle. Using the everclear to break it down as much as possible, helps to keep the nozzle from clogging if you choose the sprayer, so leave it and shake it longer.
I hope this helps, if any of you have any questions, just post. I find the glycerine alone too strong for me, just like the green dragon. This method is most excellent.
Peace... :hi
