Sorry I had to produce a number of "wizjugs" for Occupational Medicine's Dr. Ehrlich at Mt. Sinai Hospital in NYC to work on the West Point Foundry site on the periphery of the Marathon Battery EPA Superfund National Priority Site (nickel and cadmium for Nike missiles) where we uncovered the R.P. Parrott's gun platform, on grillage, for his patented rifled cannon, either the prototype or the one used for "Swamp Angel" in the incendiary bombardment of Charleston, South Carolina in 1863, described in poetry, particularly by Herman Melville and got carried away. It was found below the remains of the "Bridge Shop" remains from ca. 1912, when the Chicago Bridge and Steel Co., was there in Cold Spring, NY across the river from the West Point Military Academy. Our "wizjugs" were brown w/ white caps, were yours?
According to Wikipedia, "In 1669, German alchemist Hennig Brandt attempted to distil some kind of "life essence" from his urine, and in the process produced a white material that glowed in the dark. The phosphorus had in fact been produced from inorganic phosphate, which is a significant component of dissolved urine solids. White phosphorus is highly reactive and gives off a faint greenish glow upon uniting with oxygen. The glow observed by Brand was actually caused by the very slow burning of the phosphorus, but as he neither saw flame nor felt any heat he did not recognize it as burning."
It wasn't collected only by Confederates, though, nor was it only collected during the Civil War. (See "1776," the song where John and Abigail Adams sing about treating potassium nitrate with sodium chloride, or something like that, only Abigail won't do it until he sends her some pins.)
And no, it's not from the Civil War. The wizjug itself was from my OB's office, and the term came from the necessity of preventing confusion when reaching into the fridge.
"Can you get me some iced tea?"
"Wait! Make sure you grab the right bottle, not the wizjug."
Is this from the US Civil War? Urine was collected by the Confederacy in quantity "for the cause" which was evaporated and turned into munitions to fight the Yankees. There was some poetry written in reference to the practice.
