Member of:Alum Group
Name:Named after its discovery locality, Tschermig (now Cermniky), near Kadan, Czech Republic.


Note: Specimens frequently offered for sale of 'tschermigite' as large, good quality purple crystals on matrix are artificially created specimens made by growing crystals of this ammonium alum in a laboratory.

Godovikovite is a dehydration product of tschermigite sometimes occuring on burning coal dumps.
