Another method:
o Add magnesium chloride to the urine and a precipitant forms which is magnesium ammonium phosphate.
o Clean this precipitant with several washes until it no longer has an odor.
o This material has taken the phosphor normally found in the top oil and combined it with the ammonia found in the white earth.
Shown in the photo to left is Gustav Meyrink (1868 - 1932). He was a member of the Hermetic Order of the Golden Dawn and believed the "prime matter" to be struvite (magnesium ammonium phosphate) which is made by adding magnesium chloride to urine. It precipitates to the bottom as a white salt. Why did he believe this was the prima materia? Most likely because he witnessed it's manufacture and use in the Order and the name of the Order itself is a metaphor for morning urine.
It's interesting to note that during the time he was a member (1889) he also opened a new bank. Perhaps to funnel money from his work with transmutation? It was proven that he was a member of this Order because it's founder, William Wynn Westcott, sent him a letter which remained in his archives. It's also interesting that Westcott is the creator of the Hermitic Order of the Golden Dawn, and yet even he left the Order and made another one, the Stella Matutina. He was also a member of a Rosicrucian society.
The Amoun Temple of the Stella Matutina in London closed its doors in 1919. This was due to two members becoming schizophrenic, one of whom, a clergyman, was later to die in the mental hospital. (Mr. Lenz perhaps?)
