Ed Clopton's Photo Gallery

J0E-VAAThénardite

Searles Lake, San Bernardino Co., California, USA

Dimensions: 29 mm x 27 mm x 20 mm

Partial cubic crystal of halite 14 mm on edge replaced by pink thénardite, on a plate of thénardite. Purchased in 2006 from Hal Prior. The mineral is so hygroscopic I could not glue it to the base with white glue as I usually do--the glue didn't dry, it just dissolved the bottom surface of the specimen--so it is mounted with mounting putty. The cardstock label that has been in the box with it for 13 years is soft, damp, and blurred.
