    Is there any way to tell if the concentrate you have has been properly purged? I get my concentrates from dispensaries that get good ratings, but I have no idea how to tell if the product has been properly purged or not. I first heard that you can tell by color (best are light colored see-through) but then I heard color has a lot to do with how much trim is used - I have some products that are light gold color see-through shatter, some that are darker blonde sand-type and some that are dark green waxy blobs and a couple dark very viscous oils...

    Place some of the bho on a razor blade or dabber and hit it with a lighter. If it sparkles, it has a lot of unpurged butane.

    what do you mean "if it sparkles"? if it goes up in flames?

    Pretty much. Pure bho will just melt down if you apply heat, whereas unpurged stuff will have a visible reaction (may catch on fire and/or crackle)

    You'll hear sparkles and sizzles.

    I also put oil i suspect is under purged in a half dram jar and heat it with the torch, residual butane ime looks like larger bubbles where as terpenes tend to have smaller bubbles. Although you can risk overheating your oil like this and make it lose some of its flowery taste. At least you know its purged and then i can just scoop dabs out of my jar.

    I dont know about bho but under purged qwiso will spark and crackle when dabbed on a hot nail. Any qwiso will go up in flames if its directly heated with a torch, oil combusts once it reaches a certain temperature just like anything else. Ive purposely over purged qwiso to see if it still became engulfed in flames when heated with a torch and it did. IMO the only way to tell if its fully purged is to see if sparks on a hot nail.

    @OP I don't think the color tells anything about the presence of residual compounds being left over from the extraction in the concentrate. In general higher quality concentrates are lighter and more see through. A darker concentrate may hint that an extraction was performed poorly, but thay doesnt always hold true. If you're overly worried about your concentrates being under purged either buy/build a vacuum chamber to further purge your dispensary bought concentrates, make your own concentrates, or switch to a type of hash that isn't extracted by a solvent.

    I just tried some BHO from a local dispensary last night, well I almost tried it - I let the nail cool down too much so when I put the concentrate on it (it was kind of a oily butter texture) it simply melted with a wisp of smoke. To clean the melted oil out I put the torch to it and it really flared up with some nice sparks - I should use this product only to season nails, yes? Seems like it has a fair amount of butane left in it?

    I know the issue of purity from a medical standpoint along with risk mitigation, but does anyone have actual documentation on why butane inhalation is unhealthy/unsafe?

    (And yes, I agree that patients should have access to reliably clean, safe medicine, but I feel there's a bit of leeway (and price difference) for casual use. Unfortunately the constructs of any distinction between the two are still in the process of being fleshed out.)

    Inhalation of butane can cause euphoria, drowsiness, narcosis, asphyxia, cardiac arrhythmia, temporary memory loss and frostbite, which can result in death from asphyxiation and ventricular fibrillation. Butane is the most commonly misused volatile substance in the UK, and was the cause of 52% of "solvent related" deaths in 2000.[11] By spraying butane directly into the throat, the jet of fluid can cool rapidly to −20 °C by expansion, causing prolonged laryngospasm.[12] "Sudden sniffer's death" syndrome, first described by Bass in 1970,[13] is the most common single cause of "solvent related" death, resulting in 55% of known fatal cases.[12]
    Nitrogen dioxide, a toxic gas, results from burning butane gas and represents a human health hazard from home heaters and stoves.[14]

    what?? I call bullshit man.

    I just stick my SSTB in between my teeth , spray directly into my mouth & then I purge by gargling it.
    When i start to choke on it, I know its ready.

    and then, I dont eat it or vape it anymore.

    I 'shelve' it. (google is yr friend) Its much more efficient, but it does make a session with your mates a bit weird tho.

    You dont have to 'shelve' only 'gummy BHO' , you can 'shelve' all sorts of things. I tried buds once, but it was a bit too much like camping.

    anyhoo FC, as you were nothing to see here. :tup:




    Disclaimer:pLS DO NOT SPRAY BUTANE INTO YR MOUTH. ITS BUTANE DICKHEAD!
    But, feel free to 'shelve' whatever you like, but pls do it cause you wanna not cause I said its cool.
    Cuz its not, its fucking weird. but anyhoo, each to their own.

    From that hightimes to dab or not to dab article

    "Both Dr. Melamede and Dr. Shackelford seem to agree that it is. “I looked through the National Library of Medicine database on this, and there isn’t any evidence that inhaling residual hydrocarbons like butane are dangerous – at least in small amounts,” says Dr. Melamede. “It’s an irritant, but that’s about it"


    Further in the article they talk about a couple hospitalization cases from dabbing oil, and concluded “I’d say the least likely of all was that it had anything to do with the butane,” Dr. Melamede concurs

    Contaminants, excessive heat, and plant waxes are the bigger problem. All preventable/fixable problems :)

    some people suggest doing a qwiso wash with yr BHO at the end of the process to help remove some of the plant waxes.(or something)
    If I was going to dissolve my BHO into ISO wouldnt the need to purge the butane from the BHO become redundant due to putting it into the iso?

    has any done this or anything like this??

    so, spray the BHO into a dish, wait for the excess butane to evap.

    then just scrape it up and put into some ISO thats been in the freezer.
    Put mixture back into freezer, say overnight.
    then strain thru coffe filter to catch frozen bits we dont want.

    let evap, then scrape and enjoy.

    surely there wouldnt be any butane left because when the BHO dissolves into the ISO then the butane would be released?

    Guess, I just going to have to give it a go.
    any thoughts anyone?

    This is called winterization. I haven't done it myself yet, but have seen/tried winterized oil. It's something I'll be doing once I'm more into making BHO.

    sweet, would love to know how it turns out. Its about 4 weeks beofre my next BHO run, and I have been struggling with the purging process myself.

    Between the Ti pad being too hot sometimes & the snap crackle pop of my dabs has been doing my head in somewhat. i monitor my heat in the purging process etc quite closely, but I still often get varied results.

    I figured the ISO wash at the end would kill 2 birds with one stone so to speak.
    1) get rid of some shit in my oil i dont need.
    2) no need to add heat or worry about purging the butane out.

    cant wait for my DBV oil attachment to arrive and for my girls to hurry up & get their freak on!

    For winterization ever clear > iso if it's a feasible option

    everclear isnt available here. I use bacardi 151 for my tincture, but at $80 a bottle, there is no way i am using that to watch evap away.

    lolz- who am I? bill gates?:lol:

    whereas I have finally managed to locally source 5ltr of 99% ISO for about $40. (I have been paying $9 for 250ml)

    so,does that mean?
    If you winterize your BHO with ISO or everclear then the traditional BHO purge is redundant?

    This process seems to work for me...that's why I share. When I am blasting, I put about a shots worth of everclear in my container. The butane coming out mixes with the alcohol. You let the butane evaporate as normal but when the bubbling stops its done. The butane should be all out at this point, or just about. Just purge as usual, or if you want to refine it a bit more, throw it in the freezer for 24-28 hours, filter it (coffee filter, or whatever you have that is better), and you'll have some really clean bho.
