Cannabis Rosin(solventless hashoil)

[midwestHIGHS]

well ive been makin rosin for about the past two weeks or so out of icewater bubblehash . The bubblehash bubbles and melts but only for so long and then about half of it is left that doesnt melt or bubble at all and just burns. sooooo ive been gettin insanly good yields and all it takes is practice and bubbly hash, i found less bubbly hashs arent nearly as good and will yield very little rosin.

my yields have been about 50 percent yes 50 percent today and yesturday were the first time i got these numbers and also the first time i worked the same chunk for over an hour(scrape, re heat, apply, scrape, and repeat)

so if your not getting much on your first go dont be so discouraged work that piece a few more times. I believe if the de rosined hash still bubbles there still goods in there and can be worked more out further

so today1g bubbleicewaterhash = .5 rosin( pure full melt bubbly oil)
has the texture of glass with a carmel amber color kinda buddery a lil but not really cause it just looks that way when u touch it its brittle as fuck , its easily warmed up by your fingers to bend and shape

im also gunna be making bho soon actually tomorow ha im gunna compare the two see whats better...(yield, potency, effects, and flavor)

at first i figured bho would obvisouly yield more but shit after today with 50 percent yields using a much melty bubbly hash to begin with

hmmmmmmmmm SUPER pure concentrates rule and my lungs are thanking me

I haven't been able to give this a try yet, but I've been thinking of doing this inside of a hot vegetable oil bath instead of water--- I would monitor the temperature of the oil with a thermometer.

When I eventually get around to doing this Iam going to try with the oil first at 212°F (100°C) and than at a slightly higher temperature, somewhere in the 220°-250°F range.

I might also use a pyrex dish instead of a steel bowl.

It would be really interesting to measure the surface temperature of the bowl being used (with an infrared thermometer) while rubbing the same starting material on the same bowl at different surface temps.

worth a try a forusre funny thing is a had my canna use only thermometer right next to me and didnt even use it. but i use a singly top burner thats ceramic i believe.... what ever it is its not metal. and ive used this ol thing so much i kno what temps it will produce with boiling water and it will never get over 210 on high. so i just figured i had mine about 180 - 200. once i got a nice coat i take it off so i dont ruin any taste or potency and then finish up any spots i missed to make an even coat before it cools. i believe excessive heat effects flavor similiar to a bho purge... to much heat equal diminished taste and head effect.. usually alot more sedative effect than heady.... im assuming decarbing is taking place?

 

[midwestHIGHS]

i guess its what kinda high your after. i feel like the temps i use and bubble hash used make a very heady supppper spacey rush of high with a nice taste. minimal smell if any.

if you wanted some couchlock rosin id probally try a full indica bubblehash and higher temps. I'm not positive on this because ive only used the temps around 180 - 200, about 200 on the pot of water and prolly about 180 by the time i touch up that last few spots i missed. i know 212 is boiling... but my thermometer says 210 in my water on high...its not a full boil but pretty damn close
ima make some more tomorrow or when ever i run out of bho.. ill fug with some different temps and take some notes on effects using those higher temps.

 

[midwestHIGHS]

FUCKING BUMP!!!!
The pictures in this thread will melt your face off. Going to be making a little rosin soon out of some diesel fullmelt been a minute, going to try much lower temps then I used to use and see if it works as well as the higher temps.

nice to see this old thread getting a bump once in a while.

 

[Gray Wolf]

Yeah, this works slick too!

never understood the chemistry of what he's doing, but i always loved his bubbly pics.

I didn't see much chemistry involved, only trichome heads ruptured and the resin smeared on the rubbing surface.

The test group uniformly rated it as prime, but it is a lot of work and the yield is low.

Jump 117 did a similar one using fresh green material and glass. I'll see if I can find it.

PS: Alas, to my discredit I couldn't find it using search. Perhaps Jump or someone more gifted with the search engine can find his post on making Charus from fresh material.

If you are referring to these images, they are easily found on the link in my signature, called "Home-made Charas."

It was a purely mechanical extraction. Home modification of charas technology. Without chemicals or maneuvers with temperature.

I reported this in independent thread, but for a lack of originality it was moved to the general talks about charas.

Dat de von, it never occured to me to check your signature. Hee,hee, hee...........

Surprised that there isn't much more talk about rosin now that concentrates are starting to get more widely talk about/smoked.

Decided to give this a shot with 2.6g of some melty Critical Jack Herrer bubblehash that I made. Really easy and relatively quick to make compared to other concentrates teks (BHO/bubblehash/isohash). I ended up with 1.1g of some lovely black rosin. It does't have the same smell that the initial bubble did and it is very stable to the touch, which surprised me.

The effects of the rosin are incredible. Full on body glow with immense euphoria. Much more pronounced in terms of effect and potency that the bubblehash it came from. I can see this lasting me a hell of a long time, even with daily smoking.

I will be making rosin every single time I make bubblehash from now on, it's that good. Top quality buds into oil. Sugar-trim into bubblehash. Bubblehash into rosin.

is it possibly being decarboxylated due to the heat from the friction when rubbing it? why did compasshorn get 20% stronger thc concentration in his tests? why is the last poster saying it got stronger after this process? this is what i was asking about chemical process. how does one explain this method doing anything other then working the hash?

Wow, I haven't seen this thread in years! Thanks for the bump.

considering the temperature of the bowl and the duration the hash is worked against the bowl, I'd say that only a small percentage of the THC is being decarboxylated. I'd guess the reason for the higher THC% is simply that the resin (which contains the THC) is sticking to the sides of the bowl and contaminant (as well as some of the resin) is not..therefore the rosin collected from the sides of the bowl, naturally contains a higher THC percentage.

Well said!

The same effects apply to all pure types of hash.........when kilos of ganja starts selling for the same price as tobacco, we'll all be inhaling clean stuff like this. A few matchheads worth of pure hash gives a better high than two joints and without all that tar.

Probably not much decarboxylation, but it will concentrate the good stuff and leave the non actives behind, effectively increasing the potency of the end product.

Were the tests done with a GC or HPLC? A GC will decarboxylate the sample being tested.

 

[Waldgärtner]

Wow this looks amazing! Can you smoke the rosin in a joint (mixed with bud) or is the temperature to low to evaporate it?

 

[Hamburglar]

Cannabis Rosin(solventless hashoil)

I don't see why it wouldn't work, but based on my experience with BHO, which rosin is similar to in consistency, it's much more effective to smoke it on a screen in a dry/water pipe or on a titanium skillet.

I'll be giving the Mrs a dab of rosin for her to try as she is currently vapeing Bho in the evenings as (very effective) sleep medicine.

but how does it leave the "good stuff"? you are rubbing the chunk of hash on a warm surface, how does the magic happen? why don't the contaminates stay on the surface with the broken down trich heads? how does it separate leaf and trich head stalk matter from trich head matter?

i guess i will have to try this out to get a better idea of whats taking place.
