| 5.25" x 3.25" Lower exterior is slurry from rocks cut from the mid-Atlantic Ridge at the Kane Fracture Zone. The band above it has some iridium from the Cretacious Tertiary boundary. Interior is a glaze assembled from refined materials and the thumbwell is filled with blue sea-glass. | | | 5.25" high x 3.5" wide Says Down Deep Out Far: Earth Crust & Space Dust, K-T Band (Cretacious Tertiary Boundary). Comes with detailed information about these materials from the mid-Atlantic Ridge and the first sediment core retrieved that showed this iridium anomaly. Interior glaze of white and lip dip of copper grees are glazes assembled from refined materials. Thumbwell of seaglass. | ||

Comes with detailed information about these materials from the mid-Atlantic Ridge and the first sediment core retrieved that showed this iridium anomaly. Interior celadon is from refined materials and carbon trap from reducing atmosphere in the kiln makes an appearance of entrapped smoke.

Thumbwell of red glass, I put there with a tender thought of Earth's molten heart-like core . | ||

| 5" high x 3.25" wide Says "Earth Crust & Space Dust, Down Deep Out Far. Comes with detailed information about these materials from the mid-Atlantic Ridge and the first sediment core retrieved that showed this iridium anomaly from asteroid impact. Interior shiny white is from refined materials and a thumbwell of red glass, that I place occasionally while honoring the molten heart-like core of our planet earth. | | | 5.25" x 2.75" Lower exterior is slurry from rocks cut from the mid-Atlantic Ridge at the Kane Fracture Zone. The band above it has some iridium from the Cretacious Tertiary boundary. Interior is a celadon glaze assembled from refined materials that was in a reducing atmosphere in the kiln; unburned fuel created smoke that made the glaze bluish green, a result of trapped carbon in the glaze. The thumbwell is filled with blue sea-glass. | ||
