Earth from Space Then & Now?

10.5" x 1.5"

Would what we know as the image of Earth from space as the blue marble have been, 625 million years ago, been a white marble? I love hearing people speculate about that and this piece wears three materials and one sentence:

"....a white marble a Snowball Earth spinning above a molten core while continents drift and asteroid dust scatters and settles."

On porcelain clay: center of seaglass surrounded by Mid-Atlantic Ridge rock slurry surrounded by Namibian rock that proves global glaciation during the time some geologists call, "Snowball Earth". That's surrounded by sediment laden with K-T Band dust. Lavender rim assembled from refined materials that frames a thin wash of Earth crust slurry on the back.

Eel Grass Salt Blush & Bermuda Rise
Eel Grass Salt Blush & Bermuda Rise

7" x 14" x !.5"

Both ends were dipped into Atlantic Ocean sediment before dipping the sides into lavender glaze assembled from refined materilas. On top of that was placed a pile of eel grass that left a trail of ash and a salt blush. Some of the ash blistered and left rough patches but for someone who likes botany, chemistry and color -- this is a fun one.

Monterey Bay
Monterey Bay

4.75" high

Monterey Bay has been named by NOAA as a “Large Marine Ecosystem” and a “Marine Sanctuary” so searching the internet will give you lots of information about those designations. Important to me is it’s the only place where I was out on a ship when they collected sediment. I have several samples thanks to many people; I’ve mixed them all and they are this saturated iron reddish-brown (similar to many Pacific samples where acidic environments have dissolved froams and other carbonates that lighted some mud glazes.

Costa Rica (the only words on this one)
Costa Rica (the only words on this one)

13" x 3"

Brown interior sediment is from the core sourced from an area described to me as an accretionary prism -- words that became a question I asked to many geologists, "What is an accretionary prism?" I got many answers, including a denial tyhat there is one in the Costa Rican subduction area. Regardless, intense pressure of plates grinding might account for this finely-grained sediment that I apply evenly and that later contracts during firing and relaxes back down into this pattern.

Other glazes assembled from refined materials.
