ISO or Everclear

[ioright]

Hey everyone,

Like the title says, I am looking to do a run on 3oz of stems and shake and am debating which method will be best suited for me. I have done ISO hash numerous times before and have gotten decent results, but my end product is always fairly dark.

Is Everclear easier to work with? What advantages does it offer when making hash compared to ISO? Also, when you filter out your materials is there a good way to limit the time that plant matter has sitting with the solution in a coffee filter? I was thinking that I would strain it through multiple layers of tea towel before the coffee filter (if you think this would work / is still safe).

Last question...would a small extractor bag be safe to use with ISO? A super fine screen would allow the oils to go through while holding back plant matter in theory.

Thanks!

The second question is exactly a question I had, about limiting the amount of time that plant matterial stays in the solvent. The simple solution to that is a wire mesh sieve that you either hold over the coffee filter. or you use two containers. quikly filtering first the large plant particles. A simple kitchen flour sieve should work.

If you can use everclear i would use that, its safe for human consumption. ISO is so nasty, i used to use it, always left a nasty taste, only way i could get rid of this was basically purge at high temps, which boiled all the terps away so it had no flavor.

Both ISO and everclear have polar and non-polar properties so they both will bring in some chlorophyll which is why your oil is dark. Stems will prob always produce dark oil tho anyway. I have read everclear is more non-polar then ISO tho. Whereas butane and hexane are non-polar, much better for extracting cannabinoids in my opinion, get the good shit, leave the rest.

You can also do a longer wash in everclear compared to ISO. In ISO, 30 sec max, i would say 20 sec is better choice. If your not on your shit and leave it in for 5 extra seconds it could be bad. In everclear i have seen people do up to a 3 min wash, so you got more time to play with.

For filters, just use a metal/mesh strainer to quickly separate the material. Then after that filter threw coffee filter.

My understanding is, everclear works great in making a concentrate, but the resulting product should only be used for edibles since everclear is a grain alcohol containing sugars that should not be smoked.

i dont think there are any sugars in everclear. its 95% grain alcohol and 5% water. thats it. it should be as sugar free as any other 95%alc/5%water products. it is 190 proof after all.

sugars would be found in an alcohol of lesser percentage.

someone correct me if im wrong...?

You are correct. Everclear is as pure as it gets using normal distillation processes. It is the lower proof vodkas, rums, etc. that should be avoided.

im going to be making some QWeverclear... er... qwEC... uhhh... oil with everclear here within the next few days. i will be sure to post results w/ pics.

 

[onigiri1692]

Nice, I must have read some bum information. I read that everclear leaves behind sugars after being evaporated which caramelize and burn when set alight. I just bought a bottle of everclear to make some hash and was disappointed when I read that...glad you guys say this is false. Looking forward to seeing your results 2clicker.

 

[SpinLover1]

Everclear -190proof, same thing as 190 proof ethanol, I think?, is the stuff to use for the second solvent in double extractions. I assume that their is a good reason why it is trusted for the final extraction in the purest oils and absolutes. Also, I know ethanol is used outside of hash oil making, for all kinds of plant based extractions in other industries. Personally, out of all the solvents, I trust 190 proof ethanol, for making the cleanest product that has undetectable amounts of consumption grade (so no problem) alcohol.

what was the result with the 3 min EC wash? the same as the 20 sec ISO wash?

 

[ioright]

My typical runs have me soaking my material (ground) for about thirty seconds with agitation in ISO before using a french press to get most of the plant matter out. This brownish colored liquid is then poured through mesh coffee filter and then a regular paper coffee filter to remove all the contaminants. Generally this last filtering step takes up to 15 minutes for everything to get through the last filter. Once everything is on a Pyrex dish I will do boiling water baths until all the ISO has evaporated. I will then cover the Pyrex and put it in the freezer for fifteen minutes to make scraping easier.

It is the fifteen minutes spent sitting in the coffee filter that concerns me. I feel like this can't be good for my overall flavor in the final product. This next batch I will strain my mixture through a tea-towel before pouring it in the coffee filter, with less junk poured into the coffee filter it will drain quicker in theory. How long of a soak should I do if I were to use Everclear? Would I have to change my method in any way to accommodate the different solvent? Has anyone tried this before for making hash/oil, how does it compare to QWISO?

Thanks everyone

never tried the everclear wash myself on buds, but i would say 3 min is on the high side, just like 30 sec is on the high side with iso. I used to do two 20 sec washes with iso

Been doing a bit more research on the chemistry of ethanol/ethyl alcohol and what happens when it undergoes combustion. It turns out it produces two byproducts, three if you count the energy/heat released when combusted, the other two are carbon dioxide and water vapor. So it looks like it is alright to smoke hash/oil produced using everclear.

Here is the complete chemical equation if anyone is curious:
C2H5OH (l) + 3 O2 (g) ? 2 CO2 (g) + 3 H2O (g); (?Hc = ?1371 kJ/mol[47]) specific heat = 2.44 kJ/(kgK)

Ok alot of people have been talking about Iso and purity. This product, in its description talks specificly about vegitable oil titration, and uses that call for high purity. So Im going to post. http://www.amazon.com/Isopropyl-Alc...8P8S/ref=sr_1_1?ie=UTF8&qid=1329550135&sr=8-1

 

[weedemon]

you could drink the ever clear where as you shouldn't drink the iso!

everclear has alcohol sugars in it that will give your oil a taste though. for htat reason i would go with iso or ethanol over evercear. (unless i was making green dragon and was planning on drinking it)

 

[2clicker]

this appears to be debateable. im anxious to get the real answer on this.

 

[SpinLover1]

ethanol is made from sugar. Not sure if any sugar is left after distillation.

 

[2clicker]

ok so i am going to be doing an everclear extraction here in the next couple of days and wanted to get an answer on some things first.

how long should i quick wash/soak with everclear?

how long do you guys using Ethanol soak for?

im thinking about doing 2 batches. one at a 30 sec wash and another at 1 min wash... thoughts?

 

[mephisto]

Do 2 batches. I would not grind my material first. Freeze both the herb and the ethanol.
I bet the 1 min. wash yields more, but the 30 sec. wash will be higher grade... I am going
to extract some leftover blueberry w/ everclear. I am thinking around 45 sec. with a lot
of shaking to dislodge the good stuff. Already done several extractions thru extractor bag
w/ iso. Works great for the Rev....

 

[2clicker]

I would not grind my material first.

what about just making the nugs smaller...? not grinding them

 

[2clicker]

ok so im doing this shit tonight. here is my plan

im going to soak 4g of fresh flowers (sweet tooth) with EverClear in a jar for 45 seconds. slightly agitating it, but not really shaking. then straining that through a SS screen ive got hose clamped to the jop of the jar. then filter that through a coffee filter. evap EC and purge... but im not sure the best purge method...?

can anyone suggest a purge method for this extraction?

 

[weedemon]

hot water bath would be best imo. will take a while though.

Also regarding the OP. a good way to quickly filter your product is to use a regular sieve over top of your coffee filter setup below to catch your solvent. big material is stopped in the seive, and coffee filter is able to do it's thing withough overly long contact time.

 

[2clicker]

hot water bath would be best imo. will take a while though.

so put the phrex dish into a larger dish filled with near boiling water? should i expect it to bubble like when using butane?

 

[weedemon]

no it shouldn't boil as butane does. and not even near boiling. i know most people use tap water as hot as it will get.

it takes longer but you preserve flavour by staying sub boiling temperatures.

that is correct though. I use an electric frying pan with water and then my pyrex dish in there!

 

[2clicker]

i ended up not doing any extractions tonight. turns out i dont have the right adapter for Omi carts to Double Agent pen. i should have that soon though.

i was planning on loading the Omi carts directly after purging.

no it shouldn't boil as butane does. and not even near boiling. i know most people use tap water as hot as it will get.

it takes longer but you preserve flavour by staying sub boiling temperatures.

that is correct though. I use an electric frying pan with water and then my pyrex dish in there!

thanks.

how will i know if and when the oil is purging in the water bath? and when its done purging...? you mentioned that it would take a while. how do you measure the purge time?
