Removed for the sake of peace.

Harm reduction should IMHO start with taking about hard facts and removing myths.


If you are interested in the tek, pm me.

This tek will give you very good yields and is very safe for these reasons:

The backsalting step helps to clean the product, this extraction way is quite selective, especially when only naphtha is used as nps.

No heating is required. Heating solvents can be dangerous, a lot of harmful vapour can form that could even light our explode.
Heated solvent and heated acid or base is much more aggressive than at room temperature.
Plus it can produce very strong smell that can irritate your neighbours.

It's quite easy, because you don't need any ph-meter or indicator, not even a scale or heating device. All given amounts are just a rough guess and are not really important, you don't need to measure any thing. Just go by what you see. (Color change: gray, black, white, transparent...)

You can pause the extraction everywhere (except 14-16) for some days or even weeks if necessary.

Are you seriously putting lye into a freezer bag? that will eat into the bag and leech all sorts of bad stuff dude.

Yep, what he said. Glass or stainless steel are the widely acceptable materials for handling the materials used for dmt extraction using a base or acid solution.

Thanks for the comments.
These bags are usually made of polyethylene. They are absolutely fine for acidic or based material. Just don't use them with NPS as some NPS can indeed interfere with polyethylene.
Please check the chemical properties of polyethylene.



That's why I transferred the material from the bag to another container before the NPS extraction. I'll edit that point to make it more clear for everyone.

Most bags aren't so you can understand our concern but for the well being of everyone here on the nexus i still believe that only glass and stainless steel should be advised to be used as an extraction vessel

telling people to use a plastic bag in their extraction is not really a good idea

Sorry, but most plastic bags are made of PE (or PP). Both are good to use with sodium hydroxide as long as you don't use too high temperatures (PE) or too high concentrations of sodium hydroxide (PP).

And to be precise, the extraction starts not before point 7, after the material was moved to a different container.

The reason people are giving you grief about the bags is because the Nexus is centered around harm reduction. Putting highly caustic materials in plastic bags is asking for trouble and is an unnecessary risk.

For the sake of safety and everyone's well being who might read this thread, please do not advocate for putting lye solutions in plastic bags.

I guess I am a bit late and the party is already over/got canceled. Just for reference, I would like to add some information.

Even though plastics may be labeled as PE or PP, that does not mean that polyethylene and polypropylene are the only ingredients or constituents. Apart from the additives such as polimerizing agents, manufacturers also add various types of functional additives like stabilizers, plasticizers and fillers in order to create plastics products with different performance characteristics. Plastics that are intended for use with watery food stuffs only are often quite different from plastics that are intended for use with fatty food stuffs, because fats can leach additives from the plastic that would remain untouched by water and water-solubles. Plastics that are intended for use with solvents, or for use with strong acids or strong bases may have different requirements and characteristics in turn.

Taking any plastic and expecting it to not interact with any part of an extraction cannot be considered to be generally safe.

Regardless of the above, plastic bags are usually not mechanically robust. They tend to tear and rip easily, which can be a major hazard when containing corrosive substances. Do not use them for primary containment.

IMHO plastic bags do have a valid use for containment: Put your extraction liquids in glass jars or bottles, then wrap these in firm cloth, to contain the sharp glass shards that result from accidental glass breakage, and then finally place the cloth wrapped glass in a plastic bag (or two nested bags), to contain the liquids from seeping out.

BTW, the idea behind the tek you posted is sound, though not completely original. You are basically proposing a STB tek with integrated mini-A/B. Don't be disappointed if your first essay is not yet the golden version, most of the published teks are the result of many rewrites and polishings or are rewrites and polishings of earlier teks.
