What isa purge

Gotta love nexus, super smart people on there, but what do you expect from ndmt smokers lol

Thanks qwizo thanks to you I just made my first delicious and safely made hash. I did a simple iso for now, I let it evaporate in my spare northward facing bedroom since yesterday had a fan blowinig out a wide open window. Btw my spare room has an exterior door completely air tight. When I could barely smell iso in it this morning I gave it a hot water purge to evap the rest of the water in it (used 91% iso). Btw did every step in the dark except the last when I scraped it out in my kitchen. It came out to a golden whitish on parts hash that smoked very very nicely and barley stuck to my fingers at a room temp if I freeze it, it is a lot more manageable and doesn't stick at all. I got a lot more than whats shown on top of the jar in the pic I just set it aside in a dark place while I go to get a better razor. I'm using a broke in half double bladed razor its nice and bendable to get the round edges of my casserole dish. But I want a big bad larry razor to get the mass of it off the middle. Ne way this shit got me blasted off 1 hit on top of a ashed up bowl (very good skill learned from crack heads ash up your bowl and you can smoke oil on top of it) it was so smooth nothing rough about it and it was delicious.

Looks to me like your loving long time came full circle my friend! Verywell done enjoy! when I was in school old man said man who stand on toilet high on pot! lol!

Btw I did a second batch that didn't yield quite as well but it was pure blonde and powdery and it melted completely to liquid when smoked very lemony and delicious didn't wanna get this batch in the light at all I got a lil in the freezer waiting for me for later. The only thing I did different with this batch that I didn't with the other is I only let it sit in the trim/pop corn buds for only like 20 seconds while I agitated it (shook). filtered it very fastly in a coffee filter that I place in a pasta strainer that was on top of a metal mesh grease catch thing that stops bacon from spitting at you, over my glass casserole. I squeezed and drained it very fast and discarded the used greenery (wont be doing that any more Ima run it 2nd time). I prefer the yield and the color and taste of the stuff that I washed for roughly 40-45 seconds filtered the same exact way. Done at same temp, time, and light (shall I say dark). Just wanted to do a controlled experiment and the quicker washed stuff is deffinitly more potent but it melts very quickly and doesn't smoke quite the way I want and taste the way I want, don't get me wrong its delicious, just not what I want.

Thought I would combine some of my posts to make them better to understand...for any readers out there to stumble upon

Qwizos take on winterizing...
winterizing removes the fats,waxes and other lipophillic (fat loving)compounds. What makes them lipophillic or hydrophillic is based on polarity... butane is non polar (lipophillic) ethanol and iso are relatively polar, meaning they won't allow lipophillic substances...

Solubility is largely based on polarity and temp. so if you heat the polar ethanol or iso it will absorb the extract left from a butane wash. After freezing it the solubility of the waxes and fats decreases. These lipophillic non polar waxes precipitate as a solid out of the solution. It can then be filtered

The waxes and fats removed make up the harshness and congestive properties smoked hash oil can sometimes bring. This process does not remove terpenes and will drastically increase the quality of a butane(non polar) extract... if you start with an iso or etoh wash its not as necessary and shatter can easily be produced using a single polar wash.. iso in the middle of butane and ethanol polarity wise giving the best extract only using a single wash......but for compounds such as thca and precursory cannabinoids to move about the plant (as well as all compounds within the plant) they must be relatively polar. Because of this iso or etoh can extract a dirty product if left in solvent too long....which is why a long soak in butane that's allowed to pull every last cannabinoid and wax/fat. And then winterized to remove the wax/fats will give a better yield of quality product than iso or etoh.



Fats and waxes are highly lipophillic. For a compound to have drug likeness it must be polar to a slight degree(allowing crossing of the blood brain barrier and to be soluble in the blood).. this slight polarity helps keep them in the ethanol as all cannabinoids have a hydroxyl group when the also lipophillic fats get pulled, the fats and waxes are also larger heavier compounds which hinders solubility. winterizing is how commercial perfume/essential oils are made, and if done properly will not harm the flavor, though I should mention the waxes and fats pulled often are somewhat fragrant.. It should be noted thc itself is an aromatic monoterpene, anything affecting flavor effects potency. I do all my extracts in the dark and under 70 degrees even in the purge. 75 degrees or so is when lighter terpenes began to volatize into the air (Ialso dry/cure at 70 or under for this reason)


polarity is relative, butane does not have a polar hydroxyl group -oh while iso and etoh do . This is responsible for iso's high boiling point, even though its molecular weight is very similar to butane. and why water boils at a much higher temp, being much lighter than butane or iso. Hydrogen bonding is the strongest intra molecular force. Imfs are what determine solubility. Their is no defining line between polar and non polar. Its how polar or non polar. To find out, the biggest clue is molecular structure. ch bonds are non polar making hexane with more carbon a better non polar solvent. These hydrocarbon solvents lack the polar hydroxyl group that water iso and ever clear have.. but for them to hold cannabinoids in suspension and dissolve them they must also have a non polar side, which is why you can't winterize in water...likewise You can't winterize in a completely non polar solvent either. Iso is actually quite non polar, so is ethanol. Look at a ph index polar water is 9 iso somewhere around 4 etoh 6 and butane 0.. this is just an estimate off memory.. Etoh is best, iso will work butane will not. This is because of the waxes increasing solubility in the non polar solvents.

Put like 4 posts in one, hopefully its a bit better to read and understand...probly should of just rewrote the whole thing

Why remove it when we can now all say "refer to post #126 for all the hash related answers you need" ~~~~ I think this thread should be stickyed

We do need stickies in the concentrate section, its been mentioned a few times recently, wish we had a mod too..besides rize (no offense, and I think he's a mod)...anyway..looking good, what about the taste made like the darker longer washed oil? Jw ..

It tasted a little more like typical hash I'm used to buying. That and when I smoked it it turned a lil hard and smoked fine in my pipe. The stuff that was washed quicker melted away immediately and I don't have a proper rig to smoke it yet.

ash from smoking kief is the best

cigarette ash sucks dick.

bud ash works too.

So all asians and muslims are off chops?

So I couldn't help myself, I had to try what im callin a "freeze purge", I don't think I had enough dry ice to keep my chamber cold enough for the whole purge, but the product turned out ok i think..I don't think any butane left, or won't react at room temp or on my griddle at 110ish atleast and dabs pretty clean, taste is alot more than I expected from a landrace afghan Kush, lemon Limey, the texture is kinda like the inside of a 3 musketeers candy bar..

Damn, no feedback ? Tbh, I wasnt sure if this is groundbreaking shit or the dumbest shit ever, lol, but no feedback, damn

Haha... looks good man

I don't really understand why everyone heats their oil up so much, just a few minutes ago someone started a thread asking for bho help. Apparently his oil gets darker as he's purging on a candle warmer lol....the best oil imo comes from a cold run....

also if you were going for crystalline hash I've only personally seen it come from iso but I have heard from and seenothers get it occasionally with butane. Crystal formation is very complex and is turned to an art. The slower you freeze theoretically the bigger the crystal, but key also is keeping your solution supersaturated by subjecting it to increasingly cooler temps or slowly increasing vacuum or wind over your dish. Solvent choice, waxes, amount if particulate, temp, atmospheric pressure, time, and the fluctuation of any of these effect it. But I honestly don't know the specific parameters to turning it to a crystal powder after evap and not just glass or hopefully never sludge.

its really hard to judge that.. color looks nice and yellow. thats all i can tell :]

mind elaborating on your freeze purge?

id melt it over bowl of weed, and take a video(if you can, or just remember details, and describe melt down, bubbling, crackling, sparking. etc.. , and show us it happening) . I'd be able to give some really good feedback then..

in my process when i get a stage similar to yours, with a nice yellow muffin, i gots to melt it down at around 120F and continue purging..

needs to hear/see how that oil melts over some greens first!

unfortunately kinda hard elaborate too much since i write nothing down and extract drunk...but i put my chamber on dry ice , next time i think ill get a 5gal bucket and fill that with dry ice and put my chamber in that....but then i took some fresh blasted BHO and put it on parchment and put that on dry ice to freeze, didnt seem to get that cold so i folded up the parchment and put dry ice on top, the crushed it up as fine i could and placed in precooled chamber.. when it reached full vac it started to pop, little flakes were flying everywhere like a snow globe, i dont know if this is cause it warmed on the way to the chamber or what...but then i got a little worried id lose oil and killed the vac, then decied to just go with it n see what i get lol, turned back on the vac and let it pop n do its thing...my chamber started to warm"" as it stoped poping thats why i put the end product on heat to see if any tane left or any reaction, didnt get a pic of it fully puffed out b4 squishin togeather for some reason, but seems clean, and maybe even faster than a heat purge? so far i like it tho
EDIT:also i think if i had more dry ice and could have purged longer with the colder temps i might have gotten a kief like crystal?

interesting.. ive once made a muffin explode in my chamber.. talk about losing oil!!


i was using my freezer to chill a folded oil ball in parchment.. well.. i forgot it was in freezer, i took it out, it was rock hard cold, i throw it under vac, anddd the prettiest muffin i ever seen started to rise... well, it got bigger and bigger annddd boom! yellow snow every where...

ugh.. yaaaaa. thats my only experience in the cold purging field :]

i think there needs to be a freeze/thaw kinda thing goin on to prevent the explosion or whatever, or maybe can release pressure b4 explosion

yeee, most likely.. i would loveeeeeeeeeee to get some results in on a melt down over some greens!!!Elefafaiflweafnvcl;v pleaseeeeeeeeeeee. put that flame right on the oil :] try to get it to spark up (it shouldnt)

had my bro take a dab for ya guz, no 4th of july so thats a start, maybe could do another purge...should mention as i been playin with it its kinda became more of a traditional sap/shatter texture or whatever u call it...
