Wattevilleite: Na2Ca(SO4)2·4(H2O) (?)

Comments: White masses of wattervilleite scattered on lingite matrix. Label gives locality simply as Bischofsheim. Photographed under indirect natural light, hence the deep blue reflections and shadow areas.
Location: Einigkeit Mine, Bauersberg Mt., Bischofsheim, Rhön Mts, Franconia, Bavaria, Germany. Scale: Field of view 0.25 cm.
