The wonderful observation was made that all three red products were of the same kind. An arrangement of six metals i.e. gold, silver, copper, iron, tin, and lead in the order of increasing rate are found in Rasarnava which is of corrosion and mentioned high reactivity of sulfur with most of the metals.
