There are several methods that leap to mind.
Back in '68 I did extractions with lighter fluid, (Naphtha).
Boiled it down over an incandescent lightbulb.
When it started getting thick, we dipped the end of a cigarette in it and it wicked half way up.
Hadda make sure the Ronsonol was gone before trying to light 'em.
That was easy, it stunk.

I do not recommend that for many reasons.

You can speed the alcohol/water evap. with a fan.
Use a flat bottomed glass saucer and scrape it up with a razor blade.
The smaller and flatter the evap. vessel is, the thicker the oil will be at the bottom.

Then use "Turkey bag" squares, or wax paper to store it in the fridge.
The cold will harden it and it won't stick to the turkey bag.


All that said, you may be disappointed in the end product.
While it once was condensed resin, after it is spread thin and exposed to air, much of it will oxidise.
Oxidised resin will make you feel, um, tired.
The good news is, however much THC and CBD that is left will already be decarboxylated.


That should get you started.
Havin' fun yet?
