The freebase alkaloids were dissolved in minimal acetic acid (5%) and heated a little. 10g salt per 100mL solution was added. Crystals started crashing out. Heat was increased until the vessel was hot and all crystals dissolved, then heat reduced slowly over several hours. No crystals were observed until the next day. The bottom of the vessel had a lot of solid dark contamination. As many clean crystals as possible were removed and the picture in the post shows the result.
The rest of the sludge and crystals were removed from the vessel and as much sludge removed as possible.
The result was a different color than the first extraction shown in the first post and it smelled faintly of vinegar so another manske is being performed, separately on the pure and slightly contaminated results. In both cases this time not everything dissolved in hot water so whatever did not dissolve was filtered out.
It looks like there are red spots of some type of fluid at the top of the vessels this time, some contaminant seems to remain, if this remains as a fluid it may be removed when filtering the product. The result will be reported.
In conclusion La Alquimista has determined their faults in this extraction compared to the first time they did this.
Too much salt was used in the second extraction compared to the first. 25g salt per 100mL fluid. The salt contamination in the product came from this. La Alquimista is using less salt now. The crystals grow much smaller but this does not matter and there is no more salt contamination.
The vessels were not heated enough. Instead of pyrex La Alquimista used mason jars in the second extraction and these did not withstand heat. The mason jar broke the first time and the fluid was recovered from the sand bath which may explain the other contaminants. La Alquimista is using pyrex again.
