Costa Rican Accretionary Prism
Costa Rican Accretionary Prism

The sediment has been ground by tectonic plates scraping against each other. It's very fine-grained and after it's applied to the clay it dries and contracts and peels up like a dried riverbed cracks but then, in the kiln, it melts and relaxes back down. More about the material here.

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.

Not literally, but figuratively speaking this piece is covered with Earth crust slurry from Mid-Atlantic Ridge which, on porcelain, can be a bit sheer where thin and as it's thicker it's more metallic looking. A groove of clear sea-glass fractured and glistens in contrast to the other glazes. The center is "All".

Volcano Platter
Volcano Platter

The firing amplified the land's dynamics by causing the melting matte white glaze to flow and carry the Earth crust slurry with it, resulting in an image of a ridge growing out of spreading plates. It captures the process of magma pushing up and forcing the two plates to diverge.

The back has a continuous band of writing, including what came to me with the material.

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.
