So I did an experiment this weekend with the RxCE extract method. In the end I am very satisfied with the results, and would try it again.
For the wash step, I used some old rosin pucks and extracted them in two, one minute washes with about a cup of 95% ethanol each. I filtered this through a Büchner funnel twice.
Now, the distillation step is where things got a little weird for me. I added about 1/4" of distilled water in a pot then added the alcohol to it. It immediately went milky and I began to second guess my decision. This is the only picture I remembered to take. I was quite busy trying to follow the process as written.
I boiled away the alcohol until the remaining water was 100°C. I was left with just water and floating oil. An ice Bath got the oil to stick to the sides of the pot, and I filtered the sediments out with a paper towel. I rinsed the pot out a couple times with cold tap water.
For the rapid winterization step, I heated 3-4 ounces of ethanol on a coffee warmer and used it to clean my tools. I then added it to the pot and dissolved all the oil that was stuck to the sides. I transfered this all to a small measuring cup and put it in the freezer, along with the Büchner funnel, for a little over an hour.
After watching the latest episode of The Acolyte, I filtered the cold alcohol to remove the waxes that precipitated out of the solution.
Finally, for the decarboxylation step, I reduced the alcohol and decarboxylated the oil in the measuring cup with my fondue pot.
I got about 5 grams of RECE out of it. I lost a fair amount of it in the degumming step. I forgot to rinse the sediments and dissolve them back in. I also forgot to put some fresh alcohol in the freezer to rinse after the rapid winterization step. Next time it will be easier.
I filled a one gram vape cart. It’s pretty close to tasteless, maybe a slight hint of oil. It’s dark, I could probably have minimized that by using the Source Turbo, but I was trying to follow the steps as the author wrote them.
I will have to see if it changes viscosity or gets a burnt taste like the live rosin ones do in about a week.
