Platters and Wall Pieces
Hot Within--Snowball Earth Slush at Equator (sold)
Band of speckled warm-white on interior and exterior is Namibian rock that is evidence that Earth was fully glaciated about 700 million years ago. Red Sea is in the brown shiny glaze, lip of Galapagos and the chatter pattern is Mid-Atlantic Ridge rock slurry. Two fish in center, carved as a stamp by Alan Steinbach.
Rocks Flowing, Once Tumbled as Ice Melted, Now from Fire (SOLD)
So many stories! Even the green glass center had been red glass before firing! (must have been the basalt granules causing a local reduction?) Transformation.
Says: Earth covered by ice 635 million years ~ still spinning ~ hard crust around a molten core. HERE: basalt and glass center framed by subducting residue, spreading crust, "ALL" mud and Namibia (arrow points to rock powder on the rim).
The back is "ALL" (dips into buckets from north, south, east, west plus siliceous and carbonate materials) applied thinly.
When Rocks Melt & Tell Stories About Ice
Says, "Snowball Earth, a place and a time. Here, melted Namibian rock layers report global glaciation 635 million years ago." That's the greenish gray area between the center of seaglass and the rim of traditional glaze. Melted stone dust from the Namibian rock. Colors developed because of interactions between clay, rock glaze and kiln atmosphere.

SOLD: Converging and Diverging Plate Boundaries
Center of sea-glass is surrounded by an area of chattered porcelain clay that was glazed with rock slurry from the Kane Fracture Zone, an area of the Mid-Atlantic Ridge. Outside of that is fine-grained sediment from the Costa Rican accretionary prism, an area of subducting plates under immense pressure from friction. That evidence, the band at the rim, is speckled from a process of drying the super-finely grained mud that tectonic plates produced from friction and pressure . . . it curled as you might have seen at a dried river-bed. That dried curled sediment didn't stand a chance of remaining unchanged once the kiln atmosphere glowed brightly at yellow heat of 2300 degrees fahrenheit. Imagine! It went limp and slumped and relaxed down onto the porcelain clay that was also about to slump--but kiln went off in time to stop that and left the glistening evidence of mud turned to rock. A window into what Earth is doing beneath us now.
Branches & Root Balls - Atlantic & Pacific
Atlantic and Pacific from Monterey Bay and Emerald Basin (off Nova Scotia), sediments alternate in stripes. The lucky part is how the Emerald Basin sediment formed rivulets and then beaded up in a circular band of pooled glaze. Seaglass center.
Coverging and Diverging Plates & Snowball Earth
8.5" x 2"
Center of seaglass framed by speckled brown area of subduction sediment from a Costa Rican plate surrounded by a chattered area of Mid-Atlantic Ridge rock slurry. Rim next to words is Namibian rock that, reportedly, proves glaciation at equator 600 to 700 million years ago. Lavender rim overlaps that rock slurry, which is white.
Says, "A white marble, a Snowball Earth -- glaciers riding over drifting continents and friction forces of diving plates".
Mid-Atlantic Spreading Ridge
The back has a continuous band of writing, including what came to me with the material. See more about the material used, known among geologists as the Kane Fracture Zone.
Earth's Pushing & Pulling
"Converging diverging . . . spreading ridge here. Fissuring folding friction subducting there. Tectonics. Central creatures framed by chattered area of Mid-Atlantic Ridge rock slurry (diverging plates) framed by a band from Costa Rican accretionary prism (converging plates). Copper green and matte white and lavender glazes assembled from refined materials.
Push/Pull & Up Dynamics: 3 PLaces
Exterior's sheer silica-rich pumice mud from Havre Submarine eruption of 2012 is in contrast with front's two samples. Chatter pattern is glazed with earth crust slurry from Mid-Atlantic Ridge at Kane Fracture Zone. Fine grained brown sediment between word band and rim is from an area described to me as the Costs Rican accretionary prism. "Geo-presence" is a word I wrote to rivet myself down in to the uninterpreted evidence of it all. Materials melted on clay.
From a Seasonal Pool in Antarctica
While I glazed the sound of the word "polynya" (Russian for pool) kept rolling off my mouth in the various dialects I imagined from my Russian ancestors. Read scientist's words about the feeding frenzy of sea mammals at this polynya.
Chopping the seaglass, picking the right brush, and every other movement I make while glazing -- all seem to set loose some grace that pleases me. Why should it not be beautiful? This brown sediment glaze from a seasonal pool in Antarctica is what potter's call a "saturated iron" glaze. Center is copper green glaze framed by blue sea glass. White matte and lavender rim assembled from refined materials.
Dinosaur-Killing Cloud of Extraterrestrial . . .
As we spin on Earth, so spins the potter's wheel. As Earth wobbles, so clay on the wheel chatters. Here the vast landscape is glaze from those forces; rock slurry from mid-Atlantic Ridge and an iridium anomaly from the first sediment core that demonstrated the asteroid dust flying about the globe 65 million years ago. Where it settled is called the Cretacious-Tertiary Boundary aka the K-T Band.
Lavender glaze assembled from refined materials, used thickly and thinly on front and back. Seaglass center.
