Kalinite is a fibrous monoclinic type of alum distinct from isometric potassium alum, named in 1868.
Its name comes from Kalium (derived from Arabic: القَلْيَه al-qalyah “plant ashes”) which is the Latin name for potassium, hence its chemical symbol, "K".
A proposal to remove recognition of kalinite as a mineral species has been submitted to the International Mineralogical Association, but it is currently (March 2010) on the list of approved minerals. Many older samples, however, have been found to be potassium alum.
