Sal Ammoniac is a rare mineral composed of ammonium chloride. It is used as an ingredient in potion-making; three drachms of pulverised Sal Ammoniac are required in order to brew the complex Polyjuice Potion^[1]. According to an alchemical work dating back to the 1550s, Sal Ammoniac is used in the making of the perfect medicine, along with Salt, Urine, Vinegar and a particular Sulphur Vive.^[2][3]
