Noman's Tek Help

[owsley]

Hello All,

I did my first extraction yesterday using Noman's tek using 1.5l water/100g MHRB/100g Lye and did 4 pulls of 80ml room temperature naptha.

Put each pull into the freezer. After 15 hours in the freezer I removed the jars expecting to see crystals sticking to the side of the jars, instead the little crystal that I could see were floating in the naptha solution.

I was under the impression that the crystal should stick to the side of the jars. I've filtered the naptha through some coffee filters and I'm waiting for them to dry to see if I can scrape the crystals off them.

Should the crystals be stuck to the side of the jars, did I do something wrong?

Thanks.

Edit: Oh and my freezer is a ***** rating, so I imagine it's cold enough. I really can't see any crystals at all on the coffee filters.

First, I don't know much about precipitation. Second, you might want to stick back in the freezer and leave it for 24 or 48 hours. Make sure your freezer is set to max cold setting. Also sometimes if the solvent isn't saturated enough it won't precipitate so you have to evap half of it first. Good luck

I've already decanted all the naptha from the collection jars through coffee filters into another jar, so all the pulls are together now in one jar. Can I split this over 4 jars and try to freeze precip again?

 

[landfishd]

Sorry I'm not familiar with the tek, and not sure why the pulls are kept separate in the first place. But now that they have been combined I don't see what separating them will do since they are all mixed up now. Hopefully someone else will chime in to shed some knowledge, and until then you can probably find some answers in the FAQ.

I'm hoping since not much freeze preciped the DMT should still be suspended in the naptha right now, maybe if I give it 48 hours I might get success.

 

[DoctorMantus]

Its fine if your spice is floating in your naphtha just do what you did filter it out and let it evaporate.

 

[owsley]

Ok, I've decided I'm going to redo the extraction using the naptha from the first 4 failed pulls. I believe my problem may be that I didn't leave the naptha in the MHRB solution for long enough, I think this because I left 80ml of naptha in the MHRB solution overnight and I've just pulled it and it's very cloudy which should be an indication its full of DMT.

Sort of glad my first attempt was a failure, the resulting success will make me appreciate the resulting spice more.

Thanks Everyone.

Evaporate down to about 20%, then re-freeze and your problem will likely be solved.

 

[owsley]

Ok I'll also try evaporating one of the 80ml pulls down to 30ml then re-freezing it. How long roughly does it take for naptha to evaporate? Should I just leave it in a room? I could put it on the windowsill and expose it to some wind, maybe that would speed up the evaporation.

 

[Rastakolnikov]

I just cover mine with a pair of tights to prevent dust getting in and then put near a fan, a windowsill would work too.
Evaporation times will depend on the naptha you are using and the surface area exposed.

 

[owsley]

I've had it in a large flat glass roasting dish with lots of surface area and a fan blowing on it for 3 hours now and I've yet to see the level of naptha go down even a tiny bit, I marked the initial level with a pen.

patience...patience...it'll evap when it evaps. No sense in worrying or stressing about it. What are you gonna do, smoke dmt-laden solvent? Just keep the fan on it and have faith in the physical laws that seem to govern physical reality.

 

[owsley]

I appreciate that I'll have to be patient but at this rate I can see it taking a few days.

Then you're doing something wrong? With a fan blowing on it, naphtha should evaporate relatively quickly. Even in my earliest/most solvent laden days, a complete evaporation of hundreds of ml of solvent never took longer than overnight (~8 hours). What is your setup like?

 

[owsley]

I have the naptha in a large glass roasting dish, so the naptha (~160ml) is spread out quite thin but still a few mm deep. I have a fan blowing cold air over it. It has not decreased at all in the last 6 hours...

 

[Noman]

What kind of naptha are you using?
If it's taking that long to evaporate, I'm thinking that it might be one of the heavier products that pulls great but doesn't precipitate or evaporate for shit.
If that's not it and your freezer is really cold, then it's a saturation issue.
Take a small amount of the NP and evaporate it down on a big plate to see if there are any alks in there in the first place.
Don't throw anything away - your goods are in there somewhere.

I'm using this naptha:

[Noman]

Can't find an MSDS for that, but I've heard lots of people in the UK talk about how proper naptha is hard to find.

I don't know what the heck that stuff is, but the first thing that came up when doing a google search for the MSDS for that product was a link that included the following:

The "Fiddes" branded products imported by Roger Edwards LLC are labeled in violation of United States law in a number of ways and affecting the regulations of several United States regulatory authorities. Now known to Roger Edwards LLC are the following statutory problems:

These imported "Fiddes" branded products are in violation of US Customs country of origin labeling, particularly when this violation is correlated with the required responsible party labeling. We are not in a position of supplying or performing a correction to the manufacturers on container labeling.

These "Fiddes" branded products are in violation of a number of on container labeling required by OSHA, thus as labeled are in violation of OSHA regulations for use in the workplace.

The MSDS for "Fiddes" branded products required under the OSHA Hazards Communication Standard which we have provided for the purpose of complying with the OSHA standard are not in compliance with the OSHA standards. We are not in a position of supplying or performing a correction.

There are Hazards Labeling requirements as mandated under the US Consumer Product Safety Commission which are lacking thus labeling (s) are not in compliance. Continued sales from inventory by RELLC would be an act in violation of law once the flaws are discovered. We are not in a position of supplying or performing a correction to the manufactures on container labeling.

All "Fiddes" Supreme Wax Polish in the 400 ml and 5L size which Roger Edwards LLC imported is labeled on the products container with an incorrect Dangerous Goods number as assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods, thus identifies the incorrect hazards for the product contained within.

All cartons of all "Fiddes" products which RELLC imported are without the required proper Hazardous Materials Labeling as required under the International Dangerous Goods Code and US CFR 49 for all forms of transportation and thus shipping by RELLC cannot be done with "knowing, certifiable" compliance of the law as required of Roger Edwards LLC as a re-shipper of hazardous materials. Extensive testing of a trade secret product would be required.

Extensive labeling correction would be required to a trademarked product, to which Roger Edwards LLC has neither permission and has been denied permission and has the legal right to alter the label there on. Supplying or performing a corrective action is out of the question.

I'd see about getting yourself some different solvent...preferably something with an established history of use and reliable MSDS info...

From the company: "Fiddes Naphtha Stains are slower drying than conventional spirit based wood dyes, allowing a greater degree of flexibility when colour matching or applying on to a large surface area."
Since this stuff is a thinner for that stain, I imagine that it would be the same slower drying solvent.
