Very translucent porcelain got a big blob of soupy Earth crust slurry poured into the center. Some gassy event got frozen into the cooled bowl -- blistered and split showing tension between the refined porcelain particles and the unrefined rock slurry. Same slurry applied thinly on the exterior of the bowl fired smoothly.
Band of asteroid-laden sediment is on the inside and outside -- in a narrow band underwhich words are written.

K-T Boundary sediment is on the inside and the outside, in a band near the lip. Exterior is Earth crust slurry from the Kane Fracture Zone. Written information on paper also comes with the piece.
Interior glaze is lavender, which pops into bright blue when the clear seaglass overlapped it and melted during firing.

Center of seaglass surrounded by sediment from core with K-T Band sediment -- coordinates recorded. Exterior is from mid-Atlantic Ridge.
Bluish glaze on rim and foot were assembled from refined materials.

From the Cretacious-Tertiary Boundary, a time thought to have darkened the entire Earth after entry of an asteroid, googleable as "iridium anomaly." The sediment is fine-grained and applied heavily and then partially removed with water from the patterned clay. If you click two times more, the back image band of words describes this artifact of place and time.
Center of glass. Other glazes are lavender and black, both assembled from refined materials.

Sediment from 30°19.9’ north 157°49.4’ west 3100 to 3115 meters deep, said to contain asteroid particles. Click to see back band that says, "Sea glass framed by Earth crust from mid-Atlantic Ridge framed by dinosaur-killing cloud of extraterrestrial dust from K-T Boundary"
K-T Boundary refers to Cretacious-Tertiary band of sediment containing extraterrestrial dust deposited about 65 million years ago, also known as iridium anomaly.

 13.5" wide x 2.5" high
Center of sea glass framed by Earth crust slurry melted framed by sediment from first sediment core taken that demonstrated the K-T Band of 65 million years ago, thought to have been the big asteroid event that caused the extinction of the dinosaurs.
Other glaze is lavender matter assembled from refined materials.

A heavy coating of slurry from drillings into Earth's crust at mid-Atlantic Ridge made the texture on the shoulder of this vase under which is a band of K-T Band sediment. Words say, "Earth crust and Space dust -- K-T Band iridium. I offer keywords for searches so people can learn more if they're inclined.
Interior and belly of vase are glazed with a slip glaze from Albany New York.

Translucent porcelain clay wears K-T Boundary sediment on the inside and the outside, in a band near the lip. Exterior is Earth crust slurry from the Kane Fracture Zone. Written information on paper also comes with the piece.
Interior glaze is lavender, which pops into bright blue when the clear seaglass overlapped it and melted during firing.

On stoneware clay, with a center of seaglass, the togethering of Earth crust slurry (exterior) and asteroid dust in seafloor mud (interior and exterior bands) offers experience of vast space and time.
Rim and middle of interior are glazed with an assembly of refined materials colored with cobalt oxide, which brightens when the melted clear seaglass overlaps it.

Center is melted sea glass, surrounded by K-T Boundary material (refers to Cretacious-Tertiary band of sediment containing extraterrestrial dust deposited about 65 million years ago, also known as iridium anomaly.) Sediment is from 30°19.9’ north 157°49.4’ west 3100 to 3115 meters deep.
Interior sides and bark are slurry from drillings into Earth's crust. Click to see back band that names the coordinates of each place.
Exterior and interior sides is slurry from drillings into mid-Atlantic Ridge.
This piece can be seen and purchased at "Grenon's of Newport." where they specialize in unique -- including watches, diamonds, jewelry, and porcelains glazed with precious geological and marine samples.

Sea glass center framed by Kane Fracture Zone, framed by sediment from first core taken that demonstrated iridium anomaly. Back band reads, "Kane Fracture Zone drillings & K-T Boundary from 30° 19.’ north, 157° 49.4’ west, Longlines 44, October 1976." K-T Boundary refers to Cretacious-Tertiary band of sediment containing extraterrestrial dust deposited about 65 million years ago.

Sediment from 30°19.9’ north 157°49.4’ west 3100 to 3115 meters deep, said to contain asteroid particles.
From ship LongLines cruise 44, October 1976, Leg #1. I have this material because I made a gift to honor the studies of muds, and to memorialize Charley Hollister. I was given this material for a piece I made and donated to the Woods Hole Oceanographic Institution.
Iridium, a very rare element in the Earth's crust, is found in anomalously high concentrations in a thin geological soil layer called the Cretaceous-Tertiary boundary (often abbreviated the K-T boundary) world wide. Iridium is known to be abundant in asteroids and comet bodies, and is generally taken as evidence of a large impact about 65 million years ago, which spread Iridium-rich dust around the world.
Google "iridium anomoly" for more information about this material, taken from the first core sample known to contain it.
