Decarboxylation

[hash head]

i decarb my bubblehash and it makes a big difference in taste, smoothness, and potency.
wait till my bubble is suuuuper dry (10-14 days dry), then make a packet about half the size of a deck of cards (use high density plastic) tape it up tight, then seal a meal the packet. then 30 minutes in BOILING water, never gets burned that way. when the packet comes out i roll it a bit with a rolling pin to mix the melted hash a bit though this might not be necessary,,,,then into the freezer for 30 minutes, then peel and voila!
better than any oil i've ever made, and almost as pure as the best co2 extract (that stuff is off the hook, but i cant make it at home).
just talking about it has my tummy is grumbling for hash....

I was thinking if anyone has ever tried vacuum sealing actual dry buds and boiling them as a way to expedite a cure and decarboxylate their buds..

with the graph on the first page showing the decarboxylation occurring below 200 degrees.. I think it might be possible and beneficial?

I put my stuff (hash powder, oil, bud etc) in a sealed jar, place the jar in a low-boil water bath for 30min.

No need to use a vacuum bag, a glass jar with a proper lid is enough.

Where did you find co2 extract? I keep hearing people talk about it, but no one ever seems to be able to prove it was really co2 extract, or show me where to get it. I have seen lots of things called co2 extract, but none were.

That sounds an awful lot like a recipe for shards of glass in your eyes.

Um, no. People have been putting glass jars in boiling water since about 1800.

Otherwise know as Canning

For this tincture recipe it says to decarb at 325 for 5 minutes. I would however prefer to preserve maximum terpenoids. Gray Wolf stated he uses 250F which is what I will also use. My question is how long would I want to decarboxylate for at 250? And also is the extra time between 325 and 250 worth it for a tincture at all anyways?

Ha! Yeah I've heard of canning. I just assumed the boiling water bath part was done with the lid off or at least not fully sealed.

My bad.

Aproximately 27 minutes.

if you think boiling glass is dangerous.. lol where do you think glass bongs come from?

have you found that this process can improve potency and or taste of the buds even if you smoke them with a flame later?

I only do this with material destined for pills, and have never smoked the decarb'd product.

Good thread, I make lots of quick-wash denatured alcohol hash, and Grey Wolf has taught me a ton. I have been using an oven temp of 276*F for 7 minutes once the alcohol has all evaporated to put the final touch on it. I agree it's not necessary for baking or smoking, as both processes perform the necessary decarboxyization for you, but I just consider it to be a more "ready to use" product, good for whatever you want with no additional processing needed. Just made 90 grams of it out of a couple pounds of wet trim, it's very strong and tasty. Picked up some purple color from the trim as well.

I thought boiling sealed glass containers was dangerous. Pretty sure that's not where "glass bongs come from".

In any event, I've looked at the canning process, looks like the jars are pretty much full when sealed and processed in a water bath. I'm still dubious of the safety of boiling a mostly air-filled sealed jar though. I don't know, those glass jars are pretty tough and might take the pressure. I'd just as soon do it with the cover off though.

What evs, eye patches are cool anyways.

Aproximately 27 minutes. its funny how i couldve just looked at that graph more closely. i did look at it i just didnt realize it had a line for appr. 250 degrees. too many numbers in my face lol

thank u sir

 

[JRace]

I have never had a jar explode in many runs.
From what I have read the concern is not that the jar will explode, but it could crack.

The method I use involves not a full boil, but rather using a low boil and the jars I put in are at room temp and NOT COLD.

I will make sure to update this thread when I get my eye patch

i think mainly it has to do with putting an open flame to a glass jar would probably break it.. like if you want to boil water inside the jar and you put it on the stove.. the water keeps the inside of the jar cooler then the quickly heating outside and it can break.

(like with glass coffee pots not designed for the stove)

but when you put a glass jar into boiling water, it heats up at a lower speed and to a lower temperature (compared to an open flame).. and has a much much lower chance of breaking.

could i decarboxylate sticky hash by wrapping it in plastic (sealed) into a boiling waterbath, for 40mins, would that decarboxylate my hash enough (doing it in 10g strips at a time?)

Some decarboxylation would occur.

Check out the attached decarboxylation graph that I copied from one of Jump 117's posts.

You will note that that 212F temperature range is not close to optimum.

According to GW Pharma

According to GW Pharma

According to US 7344736, a table from which I have attached before, 105C is optimum, for 2 hours. For over 4 kilos plant material, this is 145C for 50 minutes.

P.S. The links to which I think the post below refers to have been updated.

Interesting the differences between the two studies! I look forward to studying the details of the two different studies more closely, to better understand why.

Do you have an updated url for the sites this graph came from. I got an expired message when I tried to open them.

Thanks, GW
