Central fish are framed by a self-organized pile of Earth crust slurry from the Mid-Atlantic Ridge that contracted (during drying and then firing) into these brick shapes. Click for bigger image and read that each section's origin is named on the rim.
Back says: anoxic seasonal blooms (Black Sea), upwelling magma (Mid-Atlantic Ridge surrounding center), opalescent spheres (Bering Sea), methane hydrates (exterior from Hydrate Ridge off Oregon), carbonates (Indian and Atlantic Oceans) hot-vent metallics (Galapagos and Red Sea).
Green matte and central glaze on fish are assembled from refined materials.
