When it was first produced in the factory, white phosphorus was a colorless or pale yellow, semi-translucent waxy substance with a strong pungent smell, reminiscent of garlic.
Its ignition point is extremely low, only about 40 degrees Celsius, and it could combust through friction with the air or if mishandled, with even a small amount of the powder reaching this temperature.
Thus, under normal circumstances, it could be assumed that the substance would ignite upon contact with oxygen, burning with a yellow flame while releasing dense smoke.
It could be used to combust materials that regular combustibles struggled to set on fire, capable of burning intensely even in confined spaces with low air density. Typically, the burning temperature could exceed a terrifying 1000 degrees Celsius, effectively annihilating all carbon-based life forms within its effective radius.
