Kalinite
Encyclopedia
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

Alum
Alum is both a specific chemical compound and a class of chemical compounds. The specific compound is the hydrated potassium aluminium sulfate with the formula KAl2.12H2O. The wider class of compounds known as alums have the related empirical formula, AB2.12H2O.-Chemical properties:Alums are...

Potassium alum
Potassium alum, potash alum or tawas is the potassium double sulfate of aluminium. Its chemical formula is KAl2 and it is commonly found in its dodecahydrate form as KAl2·12. Alum is the common name for this chemical compound, given the nomenclature of potassium aluminum sulfate dodecahydrate...

Melanterite
Melanterite is a mineral form of hydrous iron sulfate: FeSO4·7H2O. It is the iron analogue of the copper sulfate chalcanthite. It alters to siderotil by loss of water. It is a secondary sulfate mineral which forms from the oxidation of primary sulfide minerals such as pyrite and marcasite in the...
