Alun opaque.  Il se caractérise par un agrégat d'alun ayant un aspect de masse opaque avec un niveau de translucidité de 4>1. Il peut contenir des impuretés. 

GRADE C

Alun brut, résidu de la base du bloc, se distingue par sa pureté moindre, son aspect blanc et son absence totale de translucidité. C'est la partie la plus basique de l'alun et peut contenir de nombreuses impuretés.
