dry ice is WAY cheap
ive considered this before, i even talked with a chemist about how the added nitrogen would effect the outcome... i dont think a short contact time with a solvent thats -200 is going to be the best way about it tho ;)

personally if i was gonna do dry ice + iso... material in 5 gal bucket, then dry ice, then iso, let it set for 10min then strain it

the dry ice doesn't have to be inside the extraction tube or in contact with the extraction.

no it doesnt but its the easiest way about it... google poor mans Ln2
besides we came to the conclusion that the added nitrogen gas wouldnt be an issue as by the time the solution reached room temp it would of off gassed completely

Since you guys put what I was going going to try ou there.:wall: This is what I was thinking. basicly the dry ice is to speed up the process. I don't want the poor mans ln2 but lets say you get the iso to -32f to lock up what I dont want. (to stoned to go on further but will if you ask me.) the qw I think it would work very nicely. That's why I asked you about temps Oakley. I'm going to do this in the next day or two so If I can post my pic's up I'll show step by step what I did. For some reason since the maitanance of the site Can't post an avatar, "like", or upload anything. But I'll do my best.

I have a question. I experimented with dry ice today and ended up with what I consider slightly dirty product due to crappy silk screen. I was thinking about dissolving in ISO so I can filter it through a coffee filter. How different will this end product be than straight ISO oil? I assume the potency will be similar but will it lack flavor compared to if I has just run with ISO from the begging?

your yield will be high, and your end product great... altho since you even say it yourself its a lil dirty, expect that to translate into the oil, it will be very good oil... but you might not get the transparency you would from making it from plant material itself just due to the fact of the extremely fine pieces of leaf (increased surface area on plant matter increases contact area with solvent = more residual plant matter extracted (eg, chlorophyll)

Why you take my comment as trying to start an argument? I'm just sparking a little debate...smoke a bowl and try to have a conversation, why can't we share our different views and try to come to a agreed upon conclusion? Now that we have that aside...let's see if you can respond with out sounding like such a know it all this time.

What else exactly is in my Iso? Can you post a link that shows the distillates or contaminants in the Iso? If there were contaminants wouldn't their be some kind of residue left behind after all the alcohol has evaporated? Just a thought.



Can you explain this? 99% will dissolve the cannabinoids quicker because more alcohol is coming in contact with the marijuana. Like you said 91% has 9% water, so that water will slow down the process, will it not?



What was the point of this last paragraph? Where did I try to sound superior to you? Where did I try to start an argument?? Please highlight or quote it because I can't find it. Try to have a conversation...it's not that difficult.

OK, I think we got off on the wrong foot here man. I read "where do you get that", and I suppose I took it the wrong way, and that carried through while I read the rest of your response.

What I was trying to get at, without going into unnescessary detail, was that the 90% ISO will extract THC just fine, but it's still only the actual alcohol doing the work. That's why I said it's not actually faster. I was referring to the solvent doing it's job, not the remaining 10%. Hence my recommendation to use 99%. The PROCESS will be faster, you are right, it's just that I was trying (quite poorly I guess) to illustrate that the ISO in the 90% is just as effective, it's the remaining 10% that slows shit down.

As far as pollutants go, again, I think I must have explained myself poorly. Even water is a pollutant in ISO. Really, anything at all that is in a solvent other than the actual solvent, is a pollutant. And even in the cleanest water, there are still going to be a small amount of other dissolved particles. No link, just reality. Ain't nothin that's perfectly "clean" unless you're splittin atoms!

Hope this is more clear. I guess I should have explained that I wasn't going into heavy detail. Kinda came across as a prick there. Sorry bout that.

i had thought about the dry ice thing when i was 15... your not the first nor the last to have that "epiphany"

Thax man, now I feel a whole lot more confident about my "original thought" abilities! (thats my sarcastic humor speaking):fire:

I'm barley getting in to the chemistry of cannabis. I know how to "wash", "clean up", certin things....... so when I seen it's possible w/ hash. it peaked my intrest. for a long time I just did straight quick washes from prior experiance, had to many friends leave stuff cooking on bekers sleepin on it. you go to there house and walkin And when you leave you either stay up or sleep for 3 days. So I didn't want to do no long term evaps. iso an butane wash my go to but didn't like the harsh smoke of the butane or the black of the iso. I started studying to perfect my tech, whan I came a cross matt's Ice Wax. I fell in love w/ it! the Bay has some good ice wax makers so I went to pick some up. IMHO that method retains the best quality from the flowers, its stable looks beautiful, & aint as harsh. I don't think I'm anywhere where near as good as you in iso or matt in ice wax or Verde in bho but I study all of your guys methods and allow each time I do it be my experiance teacher learning an a curve! hahaha

just wondering...a friend of mine was talking about a potential vacuum purge after cooking off the majority of the alcohol..what are your thoughts

the concept of vacuum purging iso might work... but i doubt its gonna work the way you want it to... it works with butane well as butane's boiling point varys from -1c to 1c
where as isopropyl has a boiling point between 80-90c....

I vaccuum purge my ISO every time. It works ok, but like Oak said, the boiling point is higher, so you have to get it in the vaccuum straight off the heat.

ISO does have a higher boiling point than butane, but under a vacuum, it's something like -53 degrees celsius. I've never tried vacuum purging ISO, but so long as you don't heat the oil to the point of releasing terpenes or causing decarboxylation it shouldn't hurt anything, and will probably help.

WOW....... I finally got around to trying this method. I used the exact same method you have shown. I agree this is a great and easy method and at this point one of my favorites.

I was never one who gave a ratts ass about filtering my hash and always let a few particles get by once I would run the iso thru a filter I let it dry and then smoked away... I did try this method I alternated between heat and a fan (not a fan of heat and ISO) but I did use a heat plate to cook off some of the iso..

I have been smoking this the last few days and well I will be damned... I finally made full melt hash!! thanks!!

I allowed mine to get a bit more solid then yours did but that is an easy cure a few blasts from a lighter and this is goo gold!

any of you guys ever boiled your kief? secure it well in a cellophane bag, make sure its completely water tight, dip it in for a min and then feel the consistency of the kief; pressing it while ur feeling for the consistency. after a couple of min being under the hot water ur kief will go from a golden color to a mild brown color.

I agree. The reason I make sure it goes into the vaccuum chamber warm is because when the oil is warm it's more runny, and seems to release the bubbles a lot easier. Not very scientific, but it seems to make things go quicker, and I'm careful not to over-heat the oil.
