The mixture is wet so it can react. The process takes time, followed by quite a bit more time to dry, and is therefore unacceptable to the impa- tient addict. It can take days to completely dry, and some quivering junkies are tempted to put the paste in the oven to speed the process. As C-base begins to evaporate at about 98 deg C, this act may result in a tragic loss of base, followed by attacks by fellow basers. This method skips the extraction process.
Extraction removes a great deal of the cuts and filler, but some garbage still does get through.
Add at least .6 gram baking soda, tightly cap the vial, and shake vigorously for about one minute. Repeat several times. The reaction is slow, and can be speeded by heating the vial under hot water in your sink. The crystals are C-base, and can be either mechanicaly extracted by pouring the solution through filter papers and rinsing several times with water and dried under a lamp, or by extraction with ether. Ether is far more voilatle than gasoline, and the vapors are prone to ignition or explosion.
