Specimens for the Museum

SPOCAHP ANAR · 04-27-2008, 08:13 PM

Went to the world famous Graves mountain this weekend. Picked up two large specimens to be featured in our museum's display case when they reopen in January.
The Blue one is Kyanite; aluminum silicate-sought after for it's heat resistant properties

The multi colored one is Pyrophyllite; fibrous radiating crystals are very soft and easily damaged by fingernails raking across it. The yellow stains are from sulfur leaching out of the parent rock material combining with water to form sulfuric acid.

The kyanite was mined to produce firebrick and also used from this mine to produce ceramic tiles on the space shuttle.

Pyrophyllite is used for clay brick however this pit did not mine it.

Thanks, Spocahp. I guess they don't use much firebrick anymore, since they started making those sorry precast fireplaces! It's just not the same as a real fireplace!
