The Cake Method
This has proven to be the most useful technique yet for those who wish to extract large amounts of MHRB in a single extraction. It is known as the "Cake Method" because it utilizes alcohol, which is usually overlooked in dmt extraction, to form a concentrated "cake" of tryptamine goodness. This cake still needs further refining before use , however it DRASTICALLY reduces both the time and effort required as well the amount of materials needed to perform the extractions. Even though you are adding an extra "ingredient", things will usually add up cheaper, especially with really large extractions.
Also there are a variety of ways that the advanced worker could alter this method for a VAST array of results. For instance one could add a step with acetone (see below for the very interesting process) after the cake was made to yeild a super potent concentrate that could be smoked for effect or easily salted for alternate ingestion. The implications for long term storage here are phenomenal. One could extract 20+ pds. of bark and store it as a salted cake, basically looking like an off red brick of once molten sugar. One could create through a variety of means here, an assortment of long term storage methods. Keeping their spice safe and secure for years to come. Better still, it is now much easier for a person to buy up and work up large amounts of bark "REALLY" insuring their spice flow for years to come. Who knows when the common gateways to our sacred tryptamines will be closed.
Lets say you want to do an acid base extraction and you have 10 pounds of bark. There is no need to work it up a half a pound or a pound at a time... using dozens of jars. No need to waste pounds of lye basifying a 5 gallon jar of liquid. Imagine snowing 15-50 or more grams of DMT in a single freeze precipitation, in one jar , with ONE PULL! Yes , one pull. It most certainly is possible and here is how it works.
This method was crafted using powdered bark. It would work with shredded bark but "soak" times need to be atleast doubled, depending on the particle size of the bark. This "soak" consists of covering the powdered bark in the alcohol, making sure it is completely saturated , then adding an inch or two above it for good luck. ( I know that statement is rather generic however the author does not participate in the manufacture of illicit drugs, he merely writes about them... so he had no way to judge exact measurements.) Suffice to say that if you completely saturate the powder, and then add 1/2 that amount again.... its a safe bet that you used enough. However if using 70% or weaker alcohol, one would ofcourse have to add about 1/3 more than if say 99% was used.
The type of alcohol here can be variable. Methanol here is preffered "theoretically," by the author of this tek, although both Ethyl and Isopropyl (rubbing alcohol) will work. Note that if using Methyl alcohol, one should always make sure it is completely evaporated before any kind of ingestion because it is toxic, however it does not pose a problem with this tek. Also, with any of the alcohols the more water content, the longer the wait for evaporation. (One could evap only the alcohol and extract the remaining goo without waiting for the remaining water to evap.) The advanced worker will understand ways to greatly increase evap times and even recycle the alcohols.
This mixture of bark and alcohol is placed on low-med heat. Enough so that the mixture is kept very hot but never reaches boiling point. This container is prefferably covered to reduce evaporation of the alcohol. This mixture is allowed to sit with frequent and vigorous stirring for the course of two hours. At the end of the two hours the mixture is strained, the bark either discarded or saved for future experimentation, and the mixture goes back into the pot (or into the fridge for cold water filtration to make it even cleaner, this is if you are going for the acetone mined spice) and placed on sub boiling heat to be evaporated. A small desk fan can be used here to greatly speed up this proccess.
It was found that with 99%+, regardless of the type of alcohol ( meoh, etoh, and ipa ) that one "soak" brought out over 90 % of the alkaloids. The alcohol should be made heavily basic (koh, NaOH, but weaker bases could work) to a high ph of atleast 12+ . This makes the process efficient enough to do one "soak" and leave it at that, even further cutting the amount of labour involved!
After a few hours , (obviously the more liquid you have, the longer it takes) you are down to a thick, dark red, goo layer in the bottom. Regardless of the grade of alcohol used , as soon as there is no longer any residual odor of alcohol remaining, then it is time to remove the mixture from heat. The small fan is kept atop the pan to cool and aid in hardening of the "cake." If an inferior weaker percentage alcohol was used then this goo will take much longer to harden, as it still contains some water. Either way, if you plan to proceed with the extraction... there is no need to wait for the cake to harden. Once the alcohol has evapped you may proceed with the extraction.
Success!!! We now have a MHRB cake ready for storage or further refining. This can now be placed in a single small jar, dissolved in a minimum of water.... and extracted with a non polar solvent. HERE IS ANOTHER GREAT THING ABOUT THIS METHOD - If using either Naptha or Ether (non-petroleum ether), upon addition of the solvent to the basified mixture, the solvent will immediatly cloud because it will become saturated (can hold no more dmt). This means you can slowly add solvent until the moment it goes clear and stops being cloudy. THIS TELLS YOU TO THE ML. EXACTLY HOW MUCH SOLVENT TO USE!!!! Stick that solvent in the freezer and watch it snow like an antarctic blizzard!!!
There are two ways to proceed with this operation. 1. The alcohol is made basic at the start of the operation. This yeilds a freebase cake. If performing a traditional nps defat, then you may want to go with option 2. Acidify the alcohol from the very start. This yeilds a salted cake ready for an NPS defat. Basification of the alcohol at the start seems to be the best way to go. The yeilds and results mentioned above , the "steep" that pulls 90% + was with basic alcohol. An acidic phase was not tested quantitively (sp)? It should be just as effective however the steep time may need to be somewhat increased.
