17255: Gypsum/Glauberite
Lakeside, Great Salt Lake South Arm, Box Elder County, Utah
Cabinet - 9.6 x 6.7 x 1.8 cm (3.8 x 2.6 x 0.7 inches)
Weight - 74 grams (0.16 pounds)
Specimen status: Sold

A flat, translucent to opaque, and essentially colorless crystal, resembling an alien spaceship. Gray mud inclusions. The crystal shape is correct for glauberite, but when I tried dissolving one of these in water, a significant amount of insoluble residue was left. In addition, the Great Salt Lake frequently deposits gypsum crystals. Hence I believe these have some gypsum content as well. No damage.
