Concentrates : Cannabis Extraction/Concentrate

[SloWhite]

let me politely correct that..when TOO much heat is applied,it becomes budder,when controlled its all good

Cool deal, thanks for the info! Looks like the mat either gets alittle to hot or i left it on there to long. I think i left on to long tho, heating and cooling to many times to fast..

I think that "nail" is a titanium dabber ?

I think hes talking bout my working man finger nails.. I do have a Titanium dabber tho, no the one in these pics that just a reg steel pick..



Well i just do another run tomorrow.. Was gifted about 200g of sour diesel shake nothing special, just the bottom of a few pounders.. Be busy this weekend..

Just funin' about the "working man's" nail.

200gms of poundage shake, hmm... what do you hope/expect for an oil/shake ratio?

Happy concentrating...

Oops I stand corrected I never even noticed the working mans nail was to busy looking at the porn

[SloWhite]

what do you hope/expect for an oil/shake ratio?

1g oil to 10g shake would be nice..

From what ive been seeing, heating than cooling forces the butane bubbles out fast.

That makes sense. When things heat up they expand, and when they cool they contract. Causing the molecules around the butane bubbles to move should in theory eventually force them to the surface where the bubble can be released as the gas that it is.

Left is the SourD shake, Right is my popcorn bud/sugar trim.. Wonder why the big difference in color, anyone?

This is 10mins in hot tap water after out the freezer..




Butane bubbles escaping..

My trim..



Sour shake (this is a day older than the above)



After a nice stir, and back into the freezer after a 30min sit..

Here' my opinion based on very little experience.
There could be/are several reasons for the variation in color - strain, age of materials when processed, maturity level of trichomes when harvested, temperature fluctuations if processed (purged) separately, etc... I think it's most likely the maturity level of trichomes because as most of us know, immature trichomes are clear (slightly heady), peak are cloudy (heady), and amber are past peak (mostly body). If not this, then it may be the difference in strains. I've see pics that showed different shades of red and amber within the trichomes. Or maybe it's Mother Nature's way of showing us who really is in charge?

Enjoy your oil...

age of materials when processed

If i had to guess, would be this.. The sour shake had been collected over the last 6-8 months..

What does the oil taste/smell like after all this? Is this also removing all the terpenes?

That was decent looking shake for 6-8 months old, not that I really know what 6-8 month old shake should look like...
That probably explains, in part, your 1:10 ratio. Trichomes lost along the way, so to speak.

Good question, I'd also like to know. The longest I've been able to keep oil is 2 weeks, then it's gone, up in smoke via my lungs...

Something else I'm looking forward to trying...

Well kiddies, I'm at it again.
A couple of daze ago I took what remained of the Sweet Pink Grapefruit (15gms) and made some oil (slightly over 1gm).

After letting the oil sit for 20 minutes in hot tap water, I placed it in a preheated oven (100c) for 5min. I removed it and worked it for maybe 2min, about how long it took to start becoming thick.
While I was working the oil, I raised the temp. to 130c. I did this because I thought the temp. was too low, the oil wasn't the consistency I wanted.
I put the oil back in the oven for another 5min, checking every min. to ensure it wasn't too hot (smoking hot).
I removed the oil from the oven and scraped it onto a piece of baking paper, and worked it for a couple of minutes. Once the consistency was such to where it became futile to work, I placed the oil in the freezer (-5c).
After 2hrs in the freezer, I removed and placed it (oil on baking paper) on a piece of aluminum foil and then on to a stove top burner (set at 1).
Once the oil reached a working consistency, I worked it for about five minutes, noting extremely small bubbles bursting at the surface. Once again, time for the cold locker... Same steps - 2hrs, then remove; work it for about 5min, then back into the cold. I did this process 10 times over two days, noting different things such as the surface explosions (I used my hand held microscope and observed the oil at 30x, 60x, and 100x), and how over time the oil was becoming much darker, but not a burnt darkening, something else...
Just before I wrote this I finally took a sample to the oil and put some real heat to it. All I can say is wow, definitely a HUGE difference when compared to what I had processed the first three attempts at oil making. The taste is unique, (sorry I don't have the descriptive talents as geekymonkey), there is NO residue to speak of, and the FX are clear and up.

Thanks to USBL for sharing some of the techniques for producing quality oil.

Happy concentrating...

Your technic seems really nice, I personnaly don't take that long to make oil (for the heating/freezing/heating/... process) but I usually let it cure for several months so I'm sure all the butane is gone

This. I feel that all that heating and cooling not only removes the butane, but terpenes (flavor!) as well. I make BHO that doesn't pop, crackle, or spark and doesn't have any off flavors...but tastes like the bud it came from, only much, much more intense. When I've purged like this, by heating and cooling repeatedly, it doesn't seem to affect potency...only flavor.
