Background scale in photos is 5mm squares. Rare and stunning, this more than 500g specimen of Pink Alunite was collected in 1968 from Alum Mountain in Bulahdelah, New South Wales. The vibrant pink hue of the Alunite is a beautiful contrast against the rugged and textured surface of the specimen.
It has been worked for many years as a source of alum, to obtain which the alunite is first heated at the required temperature and then leached with water. If heated more intensely it is converted into a mixture of alumina and potassium sulfate, and in this condition, as already stated, it is useful as a potash fertilizer.
Alunite, additionally called Alum stone, is a source of the chemical known as an alum and is a mineral that is rock-forming. Alunite varies in colour from white to yellow-gray. Alunite forms from the action of sulfuric acids upon potassium feldspars that are rich a procedure called "alunitization". It is insoluble in water or weak acids,
