17254: Gypsum/Glauberite -
Lakeside, Great Salt Lake South Arm, Box Elder County, Utah
Small cabinet - 7.4 x 5.8 x 1.5 cm (2.9 x 2.3 x 0.6 inches)
Weight - 52 grams (0.11 pounds)
Specimen status: Sold

A flat, translucent and essentially colorless crystal, resembling an alien spaceship. Minor 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.
