Try to evaporate to half of the volume. I use a fan blowing toward my dish, in a ventilated area. I also put pantyhose over my dish to keep dust out. Not 100% required, but it's nice to have dust free spice.
When you get a quarter of it evaporated, blow on the naptha and it gets cloudy, put it in the freezer. If it doesn't keep evapping until you are down to half of your current volume.

If you fail, don't throw anything away. As long as you have good bark, you can always rectify mistakes later.

Alright I will try this tomarrow when I do my 4th pull. Since I am only using 100ml naphtha it will be hard to judge when ½ of it has evaporated, is there a estimated time like 20-30 minutes? OR should I just blow on it every few minutes and wait for it to cloud up. And I must confess I already made a rookie mistake and wasted the naphtha from my first pull I wasn't thinking. I filtered it through a coffee filter into a snapple bottle and ended up throwing the bottle away lol

Dude! That's sad that you threw that first pull away. Unfortunately you probably chucked a few hundred mg's of dmt. Well, live and learn.
Evaporating naptha can take awhile. I usually let my firs pull sit in front of a fan for 5 or 6 hours. Sometimes longer.

At least you have 85 mg. I don't know what method you are using to smoke it, but that could be a couple major trips, and you may find that those trips are all you need for awhile. I waited a couple months after my first time. I took time to integrate and reflect on my experience.

I don't remember your intro. Have you tried dmt yet?

So you're saying the naphtha I threw away AFTER I pulled it out of the freezer still had 100mg of spice in it? If so I am very upset with myself But no I have never tried it but I plan to start on a 10mg dose and go up from there.

Ok so I just did my 4th pull and I let the pan of naphtha sit in front of an open window with a fan blowing for maybe an hour ½ and it looks like I lost over half my naphtha. I blew on the remaining naphtha and it didn't cloud up but I still continued and put the pan in the freezer because I didn't want to lose all the naphtha.

Wow do I feel stupid! When I weighed everything out I had approx. 850mg not 85mg. I was dumb and forgot that .850g was 850mg and not 85mg LOL. I can't even imagine how bad it would be if I measured out 10mg for my first dmt trip and it was actually 100mg So after my 4th pull I have just under 1g of spice, not bad but it could have been better. I will do one last pull in a few days to try and get the last of the spice. I have been noticing that with my 3rd and 4th pulls the x-tals have a slight yellow color to them while my first 2 pulls were snowy white. I guess I'll do a recrystalization after all.

Sounds like some good results after all. I am glad you got your math straightened out. 100mg, would have been a harrowing experience. I know you had some moments of anxiety during your extraction, but now that you have conquered your first one, you should be able to relax more next time. Did you enjoy the process? I love extracting. I find it to be almost as calming and fulfilling as gardening.

Yeah I was nervous at first thinking I would mess it up and at one point when I couldn't get the right consistency right I thought I did mess it all up, but it all worked out. I did enjoy the extraction process, kinda makes you feel like a scientist lol. The only part that sucks is trying not to inhale too many naphtha fumes. I just kept holding my breath and breathing under my shirt. I will definately do this extraction again and with better results now that I got some practice

Get a small respiratory mask. One for painting / chemicals. You dont want chemicals like naphtha killing your braincells! Not to mention burning your lungs or giving you a headache!
This kind of thing:

Awesome man, thanks. I will be sure to pick one up for my next project
