Brand kept his discovery secret, as alchemists of the time did, and worked with the phosphorus trying unsuccessfully to use it to produce gold. His recipe was: [5] Let urine stand for days until it gives off a pungent smell. [4] (This step was not necessary, as later scientists discovered that fresh urine yielded the same amount of phosphorus). [6]
Phosphorus is a finite (limited) resource that is widespread in the Earth's crust and in living organisms but is relatively scarce in concentrated forms, which are not evenly distributed across the Earth. The only cost-effective production method to date is the mining of phosphate rock, but only a few countries have significant commercial reserves.
In phossy jaw patients, the forensic evidence suggested the conversion of yellow phosphorus to potent amino bisphosphonates by natural chemical reactions in the human body. Yellow phosphorus has a simple chemistry; when combined with H 2 O and CO 2 molecules from respiration and some amino acids such as lysine, bisphosphonates result. [4]
Phosphorus: 1669 H. Brand: 1669 H. Brand Prepared and isolated from urine, it was the first element whose discovery date and discoverer are recorded. [53] Its name first appears in print in the work of Georg Kaspar Kirchmayer in 1676. Recognised as an element by Lavoisier. [3] 1 Hydrogen: 1671 R. Boyle: 1671 R. Boyle
The Alchemist Discovering Phosphorus is a painting by Joseph Wright of Derby originally completed in 1771 then reworked in 1795. [1] The full title of the painting is The Alchymist, in Search of the Philosopher's Stone, Discovers Phosphorus, and prays for the successful Conclusion of his operation, as was the custom of the Ancient Chymical Astrologers.
In addition, he discovered a process similar to pasteurization, [20] along with a means of mass-producing phosphorus (1769), leading Sweden to become one of the world's leading producers of matches. Chlorine gas. Scheele made one other very important scientific discovery in 1774, arguably more revolutionary than his isolation of oxygen.

Over the centuries, the variety of harmful uses of poisons continued to increase. The means for curing these poisons also advanced in parallel. In the modern world, intentional poisoning is less common than the Middle Ages. Rather, the more common concern is the risk of accidental poisoning from everyday substances and products.
