extraction of DMT from plant materials is actually very similar to the extraction of Pseudo from pills with the large exceptions/problems that the cellulose is not in crystalline form, massive volumes, and various levels of unknowns.
several acidic extractions of the same material then pooling to work with liquid will ensure close to 100%extraction of goods.
reduction of volume is almost always a must- just reduce to a workable volume as long as the mix doesn't begin to thicken. If the volume has been reduced enough to be worked with or the mess has begun to thicken, start using various tecniques to clean out the larger molecules such as cellulose, and then continue with the process- much cleaner product will ensue.
