Ok, I washed all my trim and what not like I've done so many times before, filtered it so I ended up with a emerald green wash, just like every other time. But seeing as its so hot outside I put the dish in the sun where it turned amber. I have never put my wash in the sun to evaporate so my question is why did it turn amber?

Whut they said. The UV deprotonates the green C-55 Chlorophyll into brown C-55 Pheophytin.


It also allows the C-40 b-Carotene to show through, similar to autum leaves turning from green to yellow/reds when UV deprotonates their leaves.


All the carcasses are still there, just a different color.

UV also degrades the cannabinoids, so if you are striving for maximum potency, evaporating in the shade would preserve more of them.


Have you tried extracting with the plant material and alcohol at subzero temperatures? That will extract less of the longer chain molecules above our targeted C-22 cannabinoids.

Thanks for the info, as you can tell I'm a beginner in extracting oils. I'll try freezing my materials next time I do an extraction.

I wonder. Was that RSO?

I used to make RSO style oil as my main smoke about 25 years ago. I found it was the best way to get a decent high out of the masses of imported schwag which were readily available in Tucson back then. I still make RSO type stuff that once in a while and smoke some and enjoy the nostalgic flavor, but there were people with better, more sophisticated hash oil production techniques on Usenet back a quarter century ago too.

Often pause for threads like these.
Dearly love extracts, and wanted an
understanding of all that went with them.
Found a couple of routes which at times,
became all too interesting on their own.
Always imagined that most who were 'on the path',
found their way through High Times.
The book "Cannabis Alchemy,"and the
innovative package of gear Hoyle offered
were sure high points in my young life.
Lived with cancer for 18 years plus.
Nothing I ever read about RSO
left me feeling warm and fuzzy.
Always left me feeling like it was
yet another effort to discredit the
potentially beneficial effects that
cannabis may have.
In the same breath, I would
have gladly stood in line for
a chance to have participated
in any of Grey Wolf's projects.
Was a piece in High Times years ago
about capitalizing upon the novelty
of color to propel sales.

It depends on how you define Rick Simpson Oil. Rick was extracting what was there using painting Naptha, and then evaporating it away in a rice cooker.

We extracted the oil we were painting the inside of rolling papers with using ethanol or Coleman's at room temperature, and extracted what was there, so there are more similarities than differences.

I've seen a profound improvement in concentrate quality in the last decade, and especially in the last five years, as legal cannabis ramps up. With legalization came regulation, taxation, and quality control.

Besides improvements in concentrate quality, as IB touched on, we were mostly smoking the oil at first, followed by the hot knife, and soldering iron, et al. Now there is a surfeit of quality concentrates, as well as a plethora of keen new vaporization equipment available.

Not sure where this hand basket is headed, but I'm impressed by the increasing velocity...............

Some pictures of how we coated one paper, rubbed it against another, and repeated until we had a thin film spread evenly all over, then rolled them into joints with the oil on the inside.

The last one is the vaporizer that I built out of a couple quartz security lamps and a test tube, controlled with a dimmer switch.
