Can I make dabbable oil from alcohol tincture (boil off)?

If I boil off/evaporate off the grain alcohol that I have a buncha tincture of (multiple oz. of flower went into the tincture), would I be able to safely dab the results? No harmful residues, etc?

If I just evap it off in a casserole dish, freeze it & scrape it, would that be a good way to do it?
What consistency should I expect? A not very viscous liquid (once thawed)?

 

Thanks for the info guys.
Yeah this was made with grain alcohol and nothing else (decarbed in oven, but didn't add any lecithin or anything else).

I'll try a small batch in a pyrex/glass casserole dish.
Any particular tools I'll need to harvest it once its done? Was thinking freezing it (after its done evapping the alcohol off) and then just peeling with a butter knife or something would be fine? Or a metal spatula-type thing?
(I imagine it would take forever with the tiny head of my dab tool...)

Started about 1 fl oz of tincture (containing ~15g of flower, which oversaturated it by a good bit) in a large casserole dish. Covered maybe 1/6th-1/4th of the dish when I just poured it in, I shook the dish up a bit and got it fully covered. I think it will evap nicely.

Do I need to worry about (artificial) light hitting it? I'm evapping in my basement (no sunlight), but there are lights on when I'm down here (often). For now I've mostly covered the dish with opaque cardboard, leaving a little room for gas to escape, but this will slow things down a bit.
I'm guessing exposing to artificial light for a total of maybe 5-8 hours wouldn't hurt it much? (If not, future batches will be a bit easier)

 

Yeah it is pretty goopy. Was going to post and ask if it is safe to vape, or if I need to try to dry it out more.

Here is a picture of the dish after it had evapped for 24 hours (pre-harvest). I'm holding it vertically; the oil is gummy but quite sticky & viscous. It didn't run at all, but I can stir it in the little silicone pouch I collected it into. If I turn the pouch upside down though it isn't liquidy enough to fall out (unless I left it upside down for a few minutes).


EDIT: not sure why it won't show up... image link: https://s16.postimg.io/63dfdqwgl/IMG_20160908_195533.jpg
Gonna try a couple hits of it and see how it smokes.
If it goes well I'll start another batch; got LOTS of tincture to convert. But yeah its all decarbed...

 

Smokes nice; neutral taste with a hint of stale popcorn almost, but not quite.
Worked just fine

 

Though it does seem to leave more residue than the shatter does; I'm dabbing it at the same temps, but when I go to reheat the nail there is a whole lot more burn-off (based on size & duration of flame) than there is with shatter.

Is that ok/expected?

 

Yeah I just got a lot more (maybe 5x as much as before) out of the next fl oz I put. Didn't have a razor the first night so I used a pastry scraper, it was barely adequate and I left a lot behind. I got the remains though cause I reused the dish to evap the next batch.

I've changed my mind on the taste--its mildly gross, like AVB almost, with a hint of something else non-pleasurable that I can't place. But pretty mild taste, thankfully.
Unfortunate given how much of this I want to convert... I have something like another 8-12 more fl oz waiting, and already I have more material than ~3 g of shatter would take up.

Though as you noted, some is plant matter that doesn't vaporize. Which I wish I read before I took a big ol hit today... too big, it overflowed the cup of the nail when it started boiling, and also left behind enough (clearish, thin, like after a wax hit that doesn't fully burn off) fluid to come to the edge of the cup. When I heated the nail back up, I got a flame almost the size of a half-way blown up balloon. I saw a crust form & break in the nail, and ash went everywhere... pretty gross.

 

So right now it is in a silicon pouch container
that has 6 maybe 1tbsp sized cups, and one bigger cup (maybe 2.5 tbsp)
Its spread across 2 of the 1tbsp cups (taking up most of one, and maybe 1/3rd of another)

Would I need to take the harvested stuff back out of it and smear it on a larger surface area to evap more?
Can I just leave it open to the air and stir it every now and then, wait like a week, stirring a few times a day?
Or should I just ditch these, and let the next batch sit out in the casserole dish for a couple days instead of just 24 hours, and see how much of a diff it makes?

Also, if I wanted to flavor this stuff so it didn't taste so nasty, is there a good vape-safe mint flavor I can get online somewhere? Would it make the mix too liquidy if I mixed that into the oil?

 

Nope just a regular toaster. I have a hotplate that I use to concentrate tincture (boil off in large mason jars). I have a gas stove. I have a microwave. I have lighters and a butane torch.
Those are my heat sources.
