Doesnt the process of making the rosin already decarb it?

Nah, it takes about 30 minutes @ 250F to decarb.

For pressing hash, try using a small amount of pressure until the hash turns into a brick or patty first, then just ease into it until it starts juicing, not gonna need near as much pressure as flower. What press are you using? The coffee filters are probably giving you some trouble. If it's bursting at the very end perhaps you are just applying too much pressure. You could also double bag it, would steal a little yield, but less than dealing with a blowout.

Im just using a clamp and hair straightener ive also tried the RosinBhomb but havent had much success either way. And the hash ive been using is like a sticky sand so i hand form it into a paddy then wrap it up in the paarmenth, i try starting with low slow pressure and then slowly increase over time but by the time im done and go to check it its usually blown out at one corner. I do slowly increase the preassure on the clamp until i cant press it anymore so maybe i shouldnt be going that far with it?


and yeah but doesnt decarb time and possible temp also depend on the amount of material and the consistency of that material? Like for instance if your decarbing like 14 grams of Hash lets say at 250 for 30 mins like you mentioned you wouldnt decarb 2-3 grams at 250 for 30 mins also because its gonna cook it more and faster as theres less material to heat.

Also pressure and temperature are related. And i see people saying theyre using starting temps around 200+ and as you increase the pressure being used the temperature is being raised so while it may not fully be decarbing it, it is definitely getting decarbed somewhat especially when pressing lower amounts.

In my experience it pretty much takes the same amount of time whether I'm decarbing a gram or an ounce. You can tell visually when its done. Of course surface area of the jar and other things may affect decarb time slightly but its generally very similar. Figure that an 18" pizza isn't really going to take longer to cook than a 12" pie.

The temperature on the load might change but the plates aren't going to get hotter just because the load is under pressure.

And analytical testing shows less than 5% decarb on rosin, and that was info from a few years ago, probably even less with newer rosin techniques.

I can confirm very little decarboxylation on rosin. Even pressed pucks, which would have had the most heat applied to them, after a grain alcohol wash decarboxylates like crazy. I decarboxlate my extracts at 275F in folded parchment paper on a small aluminum baking sheet. Usually its done bubbling in under 10 minutes.

Does anyone have any advise for avoiding blow outs. Im pressing hash, I mess with it so its like a piece of flat chewing gum and then wrap it up in either a unbleached coffee filter or a micro bag.

When I press my hash I use stainless steel screens with 42μm mesh. I place 0.2 - 0.5g of hash in in the middle of the screen and fold it once all over, at the remaining three open sides I make only small folds to avoid that the hash can blow out but don't fold over the hash again. so I have an envelope with one nice side and 3 folded sides.
I then press with the nice side pointing down and the rosin squeezes out onto the parchment, the hash stays in the screen.

but i'm just using hair straightener with normal hand press power, using clamps or more force would also deform the mesh and cause blowouts I could imagine.

In my experience there is no need for the big pressure on hash, it will pour out of the mesh with a lot less force compared to flowers :)

I've taken fresh squeezed rosin and quickly melted it into coconut oil at the lowest heat possible to fill cannacaps up just to see how thca would work as medicine. As it turned out I caught quite a buzz. Since then I've side by side compared decarbing rosin in the oven to no decarbing at all and only found slight differences in the caps.

When cannabis decarbs it isn't an all at once thing, so it makes sense rosin has portions of both decarbed thc and thca. And @Mynameismud makes a good point not to ignore pressure while focusing just on heat. (i use a twenty ton press) The only way to really tell would be to have it tested.

You have lab tests? IMO thats the only real way to confirm if decarboxylation has happened. Bubbles are a nice visual clue but thats all they are. You wouldnt put in a scientific paper that “i can confirm theres no decarboxylation happeneing because when i do something else i see bubbles”

Yeah makes sense. I tend to only buy really high end 6* full melt. It doesnt really need to be rosined i just like to clean it up a lil and prefer the consistancy over a sticky sand. I dont like to waste any and when i can get the clamps to work and not blow out I can get back usually 90-95%... I dont have that much experience though so i started getting blowouts and couldnt figure it out and just gave up

I've only seen lab testing online, nothing that I would put my money on 100%. We cannot test in Colorado unless we are a licensed facility, so at this time the best I have to go on is years of experiencing decarboxylating both rosin and hydrocarbon extracts. Visually, it seems to me that the vast majority of THC is still in acidic form.

I did dig up this lab test, it's a couple of years old. I cannot comment on the reliability of this result but it's similar to what I've seen posted on the years past.

I always decarb by eye, watching bubbles in the oven as i sit in front of it for like 20-30 mins depending on amount/surface area, i would very much say that these "bubbles" are a good indicator of when the decarbing is done, my edibles are on point everytime xD

Cool info on the terp seperation layer thing in the jar? So thats whats happening, hmmmmmmm

Have you dabbed decarbed rosin? I have, and I think the decarbed was stronger. Very non scientific, especially as I was actively sampling, but that's what a friend and I thought. It doesn't make sense to me, but we both thought that. The sacrifices we make in the name of science, lol.

Yes, but my sample was pretty weak even prior to decarb, so I didn't have the same experience. Most of my really good rosin I'm too stingy to put into decarb because the flavors have been so good! Next time I make some edibles I'll sneak a dab and give it a shot.

I wonder how it would be if you did like half a dab of the decarb + half a dab of rosin, bring the entourage in with the terps?

Frankly most of the rosin I have right now is so strong I have had to lay down to recover if I get an extra hit that I didn't expect. I can't imagine getting much higher.

One of my first RSO runs I got so high at dinner, with my then 90 yr old mother, that I stopped eating to nap. My wife wasn't pleased, lol, but I just couldn't function for a while.

So with the 0.877 decarboxylation factor of THCa theres 63.99% total THC in the sample and 10.1% of that is already decarboxylated.

That means by simply pressing whatever material they did for however long (lets say 200 degrees F for 15-20 seconds just a random guess) that 16% of the total in the sample was decarboxylated Without knowing any of the variables used to press it Id say thats more than “very little decarboxylation happening”
I always decarb by eye, watching bubbles in the oven as i sit in front of it for like 20-30 mins depending on amount/surface area, i would very much say that these "bubbles" are a good indicator of when the decarbing is done, my edibles are on point everytime xD

For sure! Its definitely a great indicator and can be used to gauge where youre at. But you cant really say with 100% certainty that it is fully decarbed because you dont see bubbles or very little decarboxylation is happening because after i press i put it in the oven and still see bubbles

The only way to say with certainty that something is happening in a reaction is to test the final products otherwise its all just heresay and opinions

Here's my press this morning of some Sour Diesel ...
- 5g in 1.25g out.
- pressed at 205F as at 195F it was auto-buddering and going to a crumble within a day (we'll see what happens in the coming days but seems like a nice consistency right now :) )
- 3000 psi (45mm dia ram @ 1.5tons ... and funny enough, a 2" width bag, bottle-tech style, yields ~45mm diameter puck once pressed :) ... makes the math easy as that means the reading on the gauge is the same as @ the puck ... I don't have to convert from the ram tons to PSI and then use the puck size to calculate the PSI on the puck based on the reading of the ram :) )

You can order a pack of stainless steel square or disc filters for a few bucks at most from Amazon or eBay. They're for open blasting or column filters. Easily reused.

Pressing hash with coffee filters is possible but tricky. I did it for a few monthes. Double wrap was a must unless it was super melty. I usually cut away most of the plate to allow the rosin to flow away and to more easily watch the melt. Preheating with mild pressure helps.

Can i remove the taste from my rosin by heating on the plates over night?,
Ive had quite enough of this citrus / lime ,

Anyone have tried this? recommended temps for terp removal, lol? :D

A while ago I seen a u tube video where someone claimed to turn rosin into shatter. He put the rosin in a folded parchment paper, and ran a hair straightener over it several times and it got hard like shatter. I bet that would work for you.

Does your girl have a hair straightener you can try with? Tell her Stu suggested it, lol.

You could just sit it out a few days too. Terps will evaporite eventually.

I don't doubt you can alter the stability of the material and remove terps, but you are inevitably going to burn off some good canabiniods in the process. Don't think just by going slow and low, you are only going to isolate and remove just the flavor- more goodness will come out with it.

Experimented with this last night :

I left 0.5g of some overly terpy lemon ice flower rosin inside a 7ml jar on the plates, at 145f for around 10 hours.

When i got back to it, it was still perfectly bright yellow, but the consistency had changed from the ultra gooey to a more "easy to control" type of consistency

the taste was much lower on the lemon/citrus, and the effect seemed to WAY more stoney this time,
I had been getting enough of the "high" feeling and the strong lemony taste from every hit these past few days, so this was really a blessing to me!!
:D

If you know anyone with a Nova, they make decarbing incredibly easy.

I have access to a lot of fluff from a single strain. At one time I had over 12 samples of different pressure and heat combos. No matter which of them I decarb, they all come out the same.

A little darker, slightly less terps, but that I'm dependant on others opinions, my nose doesn't smell well. And always the same consistency, very sticky and stringy, but easy to work with.

A couple unwatched hours in a silicone dish with the lid sitting lightly on top and it's done!

This was a high pressure sample. This is after pulling a few small dabs off and squeezing the sides to center it.
