Recently performed my first ever extraction with ACRB/Lye/Naptha tek from PsychonautWiki.

After my first pull, I poured the freezing naptha from the crystallization jar back into the acacia cocktail shaker jar through a plastic funnel to re use for another pull.

Is that brief naptha/plastic contact enough to worry about? I can't seem to find what type of plastic the funnel is, it was super cheap from amazon. I have not used anything beyond the first pull that didn't touch the plastic yet...

Glass or stainless steel would be better, the latter having the advantage of being virtually unbreakable, the former having arguably superior acid (but not alkali) resistance. You'll be fine this once, though! Yours will likeliest be either HDPE or polypropylene (PP). There may be code marking which will help you to establish this. PP would have a number 5 marked on it (probably, but I never quite trust the cheap stuff!)

Stainless steel funnels can typically be found in the canning section of stores that have canning sections, for a quite reasonable price. I have three, each suited to different purposes.

Awesome, thanks for easing my mind! Why did you end up going with metal instead of glass?

While I'm here, another question - I let my first pull dry maybe 16 hr, spread out on a plate as much as I dared (won't use a giant plate next time) and got perhaps 3/4 goo to 1/4 crystals. Tested the goo and it was the real deal, stronger than the crystals. However over the next week or so the goo dried further into a less liquidy/more waxy residue....is it possible I ingested some naptha when it was still more goopy? Do I need to research rewashing the crystals to further purify them?

Thanks!

16 hours seems good enough, it's common for DMT goo to turn waxy, crystallize and solidify, if you keep collecting and spreading your goo on a glass dish to dry, it will solidify
goo is good but if you want just crystals you can easily clean it up

So you wouldn't be worried about the naptha content then? Frankly I don't care much what it looks like as long as it's potent and not toxic. Is there a good reason to take the time to convert to crystals?

Thanks!

there shouldn't be any naphtha after 16 hours of fan drying, and now after a week.. does it have naphtha smell?
the only problem with goo/wax is that it's not as easy to measure and handle your doses as with crystals, i make changa or enhanced leaf with goo and it's perfect

I have glass funnels too! Porcelain as well. And plastic... Possibly even brass and copper somewhere.

But, as I say, steel doesn't break so easily.

Hmm I didn't fan dry it, just air dried. Honestly I have a little trouble telling the smell of the naptha from the smell of the spice...the naptha smell is definitely obvious at first, but even after a week it smells...similar. But much less pungent and obviously naptha like. I mean I'm not dead or sickly so I think I'm probably fine...will add a fan in the future.

So far I've just eyeballed it on a dab tool and used a dab rig. How do you even measure milligrams of something so sticky? My most precise scale goes down to tenths of grams. Decigrams I suppose. I can't picture how one would be able to measure 50mg or whatever and then get all 50 mg back off the scale to whatever ingestion device...perhaps I'm looking at it from the wrong angle. And I have yet to delve into figuring out what changa/enhanced leaf are. Noob alert

Steel funnel here I come! Brass and copper eh? Different chemical resistances?

No, I found them in a pile of junk!

Haha awesome!

Depending on the capacity of the scale and the weight of your ingestion device and your container of spice, there are a couple tricks:

Put the ingestion device (maybe a glass dish in the case of nectar collector) on the scale and tare it. Make sure the ingestion device does not exceed the capacity of your scale. Then add material directly to the ingestion device and the scale will display the amount of material added.

Put your supply on the scale (in its container, of course) and tare it. As always, make sure you aren't exceeding the total capacity of the scale. Remove material from your supply and the scale will go into negatives, reflecting how much material you've removed.

Or just tare the blade you use to apply the goo, and measure that when loaded before applying to your smoking/vaping device.

Any suggestions for scales that are trustworthy at an adequate precision level?

What Scale Do You Use?

There are a lot of good suggestions in that thread. Be sure to take advantage of the search function and/or google to find more information. There are many threads to be had about scales with a little bit of digging! Good luck!

Awesome, thank you! To be honest I'm just a little nervous about my ip being attached to a bunch of searches about illegal things (not that scales are illegal, but they go hand in hand) and getting raided or some other apocalyptic thing. I'm pretty sure I'm just being paranoid...but what if I'm not
