Sulfur in Drill Core
Large Cabinet, 24.0 x 13.0 x 13.0 cm
Comanche Creek Mine, Pecos Co., Texas, USA

Few minerals from Texas really excite. Among them, these drill cores with actual sulfur crystals and pockets in them are as much cultural as mineral collectible items. We see only a few as they turn up from old collections. In the old days, they used to get these in the drill cores in South Texas as they punctured through salt domes looking for oil. These made for the classic gift for oil executives and so many were preserved as desk ornaments - the world's most expensive paperweights, if you count the drilling cost! This particular specimen, featuring so many turns of the drill bit through the rock, is unusual - I have never seen a good one so large, with nice pockets of crystals. Usually, the survivors are in the 4-6 inch range. This piece is a giant among them. It is a very interesting conversation piece, and a fine Texas sulfur too. Joe Budd photos.
