The cool, greenish glow of phosphorus is caused by its reaction with oxygen, but it doesnt take much for this reaction to accelerate and develop into a fire, as the 17th century chemist Nicolas Lemery found out: After some experiments made one day at my house upon the phosphorus, a little piece of it being left negligently upon the table in my chamber, the maid making the bed took it up in the bedclothes she had put on the table, not seeing the little piece. NaHCO3 + heat -> Na2CO3 + CO2 . Commercially it is extracted from its chief ore, bauxite (Al 2 O 3.2H 2 O).
