Slurry from the Kane Fracture Zone is what I have. Where’s that? How did I get it? Drillings into the Mid-Atlantic Ridge were brought to land and the rocks were cut with water for lubrication. The cut produced fine rock powder in a slurry, which I melt into glaze. This might be my favorite — Earth’s crust. The picture shows two sides of a piece of the rock sample given to me by Jessica Warren. Following the photo is a description of the rock by the man who gave me the slurry:
Eben Franks wrote: “. . . . from mid-Atlantic Ridge – Research Vessel Knorr 180 – 2. 23.5° North and 45° West. Cruise was Nov. 14 to Dec. 17th, 2004. 2000 to 3600 meters depth, age between 1.5 and 2.5 million years. Glop from rock saws, high in manganese. It has lots of peridotite, serpentine, basalt, and olivine gabbro. It is mostly volcanic in nature.”
“It has spent significant time in Hell, meaning that it is from rocks that were buried deeply within the ocean crust, under immense pressure and high temperature – the very crucible of ocean crust formation. Some of it is derived from rocks from the mantle of of the Earth, below the ocean crust . . . from the top of the magma chamber. The mantle is exposed at this location, which is called the Kane Megamullion.”
Here are two photos of how different the material can be after it’s fired:
There are many pieces available in my on-line store; they’re in several sections because I use it so much (more than any other material). I call it Earth’s crust, Mid-Atlantic Ridge and Kane Fracture Zone.
