When I blast my product it looks really nice I can whip it up into a nice golden yellow badder then after I put it into the vaccum Chamber I use my household oven set at 40c and then run the vaccum chamber to -27hg
My oil comes out looking very dark when I’m clumps and sticky now it also won’t whip up
First pics are 1g out the batch whipped up and (not vacced) (still full of solvent )
Stop open blasting. Do some research and get yourself a closed loop if you still want to make BHO.
It is certainly possible to burn the oil, and if it were to decarb you wouldn’t be able to whip it. However, 40c isn’t really hot enough to darken product like that or decarb without a significant amount of time. Is it possible you’re heating the oil beyond what you think?
Pancake griddles and heat mats were pretty common with the old stock pot vacuum chambers. Used vacuum ovens are pretty cheap these days too.
Also, don’t blast or place the oil straight into the chamber, it should be in a jar/dish or on some parchment.
The heat from the oven comes from the bottom I just placed my vac onto the bottom and set oven at 40c I would hit the vac when I noticed the oil had liquified do you think cause the chamber was sitting on the heat source for quite a while this could of burned the oil as even no the oven is set at 40c im unsure if this is accurate as the bottom of my chamber was getting quite hot where I could only touch it for a couple of seconds
Definitely sounds hotter than 40c. A temp probe or IR gun could give you a better idea.
Heat mats tend to have better temp control at that range and shouldn’t overshoot like a convection oven. Placing the oil on a ceramic tile as @Roguelab suggested will disperse the heat more evenly and slow any fluctuations.
It’s been quite a few years since I’ve made BHO but from what I’m seeing and what you have said it is quite possible that that’s just the color you will get. What I mean is when your BHO is still full of gas bubbles, even if it is extremely dark when it settles down it will look golden until then.
@ShadowtegaN1 / @Smokeyjoe2023 : Although your extract likely saw temps that were high enough to cause some darkening, open blasting simply doesn’t allow you to control your solvent or biomass temps, or your residence time (time the weed is “residing” in solvent), so you’re essentially never going to get extracts like you see on Instagram.
nor does it allow things like dewaxing or CRC, which most of the extracts you’re comparing yours to have been subjected to.
When we bring in biomass from new farms, we do micro extractions (20-30g), and send those out for pesticide testing.
They almost always look worse that what you made…primarily because they are done with rm temp solvent on rm temp biomass.
My bho has turned into crumble looks very good but I’m 100% certain it’s still full of butane
I have been vac pumping the oil at room temperature for around 3 days my heat mat arrived today I set it to 40c and placed my chamber on top the oil did not liquify instead just turned to a crumble when I’m pumping the vac to -28hg it’s not blowing up just staying the same shape etc
If anybody has any techniques for me that would be grateful I have these at my disposal
Here’s the method I used if anybody could tell me where I went wrong would be highly appreciated thanks
I blasted into a baller jar and let the tane evaporate outside on its own I then whipped it up for 2 days while in the baller jar after 2 days I removed and placed into vac chamber I pumped to -28hg and released at room temperature for 3 days the oil where rising and going like a muffin shape but still sparks like mad when I put a flame to it.
My heat mat arrived this morning and I set it to 42c and placed my chamber on top of it my oil turned to a crumble type of texture the oil is now doing nothing at all inside the chamber just keeping its shape and form even on a 42c heat mat
Also if Could anybody give me a better method thanks
