Tschermigite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(NH4)Al(SO4)2 · 12H2O
System:
Isometric
Colour:
Colourless, white; ...

Member of:
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.
