Picture of How to make white phosphorus
White phosphorus in a alliotrope of phophorus. It is highly toxic and can ignite when exposed to air.
Here are some materials and chemicals you will need to make white phosphorus: Glass retort
Glass container
Eye protection
Breathing mask or fume hood
Gloves
Butane torch
Tripod for glass retort
Table spoon
Chemical:
Water
Old urine
Cinnimon powder
Charcoal dust

Step 1: Step 1

Let the urine sit out for at least 7 days. Then mix in 2 table spoons of cinnimon powder and charcoal dust and stir.

Step 2: Step 2

Pour the mixture into a glass retort with the glass tube leading into the glass container filled with plain water. Heat the glass retort with the butane torch until it bubbles up into the glass container. Wear the eyeprotection, gloves and protective clothing at all times.

Step 3: Step 3

Once the vapors have collected on the bottom of glass container, you will have made white phosphorus. If you take the phosphorus out, be preparied for it to ignite. Also, it will slowly turn into red phosphorus if left in the water for too long. It will be far more stable than white phosphorus, but still take caution.

I *highly* doubt this will work. In fact I am 99.9% sure this is
nonsense and never tried by the author, I am just being polite. First
off urine is a very poor source of phosphate, sure it was used the first
time in the 17th century but you need hundreds of liters. This is just r
reduction of phosphate, so why not use pure tricalcium phosphate
fertilizer? And the charred cinnamon thing must be a bad joke.

Secondly
the reduction is carried out at 1200°C, a glass retort cannot be used.
Early experiments used clay vessels. Due to the highly toxic nature of
phosphorus and the inherent dangers of handling such an element, that
also spontaneously ignites in air, at white hot temperatures, surely it
is unnecessary to point out that such a venture is completely foolish?

Good
information and expermental work on preparing elemental white
phosphorus can be found at the sciencemadness forum under the section
Chemistry in General. Note that this is suitable for well-trained,
highly experienced lab workers only.

A very small amount of white
phosphorus for demonstration purposes can be obtained by strongly
heating the crude red phosphorus/glass mixture obtained from treating
hundreds of matchbooik strikers with all possible solvents (elemental
phosphorus dissolves in none but carbon disulfide) in a dry, oxygen-free
environment. The thick white fumes, when captured and condensed, give
rise to a small amount of white phosphorus.

This is the method used by Hennig Brand in the 17th century when he discovered the element phosphorus. He obtained 1 gram from 120 GALLONS of stale urine. The piece shown in the jar in your photo would probably have required over 1000 gallons to produce by this method.

Did it work for you? Did you have any issues? Have any of your own pictures?
