At least one of the terpenes definitely glow blue and it’s visible especially when they’re concentrated! The pigment tracker can see it in concentrated terpene extracts or distillates, though the plant pigments tend to dominate if they are present

I think I still have it somewhere

Treating crude ethanol extract with T-41 scrub at room temp totally removes green glow. Interesting……

For this kind of thing the pigment tracker is really useful.

I was able to separate out the green glow without absorbent on the other portion that I didn’t scrub. I got the green glow to go to the bottom layer and the top layer was yellow glow. I vac oven it and it came out very fragrant like a strong pineapple. Probably high ocimene content which is weird because that shouldn’t have gone to the top layer. Maybe something else pineapple smelling but polar???

There’s a few more in the channel if you wanna check em out. It’s a good way to see how the flow went in your crc and help better dial in the process

These layers are great! What do they look like under white light? Sometimes the blue glow combines with a yellow colors to create a dull green shade but I can’t tell if that’s what’s happening here. Is the shatter the top layer?
Under white light the top layer was yellow. This was a first for me because 99 percent of my white light yellow fractions glow green usually.
@AlexSiegel The bottom layer was brownish red under white light.
The final product wasn’t exactly shatter, more of a pull and snap I’d say. It from the unfiltered ethanol crude extracted cold from that beaker in the previous pic. Not bho or anything. I actually don’t have any BHO experience. I’d usually just do scrubs or change the water content of the ethanol to make stuff drop out.

So like you can extract with 200 proof ethanol and dilute it down to 70ish percent and the red precipitates and you have green left behind. Add more water carefully to get closer to 66 percent and brown drops out and you get like a neon green left behind. Go super slow and get close to 50 percent and the green drops out and you get yellow. If you go too fast everything drops out even if you don’t go past 50 percent water.

If you remove the yellow layer when your at 50:50, then replenish the beaker or whatever with more 50:50 then slowly add water till you hit around 30 percent, more crashes, but then this weird pink stuff (under white light) gets washed out of the bottom layer. It smells bad and I rotoed it and it’s like nothing. Then I add water until there’s less than 10 percent eth and call that the last wash, the wash is white and cloudy and smells like lawn trimmings, maybe aldehydes like the heptanal and hexanal seen in concentrate terps?
The bottom layer goes from muddy to a tan color, and turns into a flavorless odorless crumble in the vac oven.

Seems like if you want to do this at scale you want to remove the ethanol from your original extraction tincture, then reintroduce just enough ethanol to dissolve the oil. You wouldn’t want to deal with reproofing 100s of gallons of your precious solvent.

Wow that sounds awesome. Sounds like you’re removing the pigments in order of polarity along with a lot of other junk. I’m surprised that works!
In my experience less than 70% ethanol tends to gel out the cannabinoids but I don’t have a lot of experience with it

I thought so to for a bit but then I tried adding the water really slowly dropwise with lots of stirring and found even 100proof can hold onto cannabinoids. I noticed when I would go too fast literally everything would crash out like the cannabinoids “snow ball” or something.
